About the Book

When Tough Cookies Crumble

Two tough cookies. Breaking barriers in careers and love. Until one is murdered…

Janice Starr and Eva Booker became best friends when they met as soldiers in the Women’s Army Corp in Korea in 1978. In a time of rapid social change, they tested the limits of women’s liberation and the sexual revolution.

After they moved to Washington D.C. together, Janice and Eva supported each other as they faced the challenges of continuing their military careers in the Army Reserves, navigating jobs, going to school, and dating. Their friendship went through ups and downs, but their bond was never broken.

In the summer of 1981, Janice moved to southern Virginia on her own. Three months later she disappeared without a trace. Eva knew who was responsible for Janice’s disappearance, but the only one who believed her was Detective Kay Lewis. Another tough cookie, Detective Lewis overcame the obstacles put in her way by her colleagues and superiors to pursue Janice’s killer and find Janice.

Interview with Eva Nevarez St. John, author of When Tough Cookies Crumble

When Tough Cookies Crumble is based on your own personal experiences. What inspired you to turn them into a book?

The book is about the murder of one of my best friends in 1981. The lead detective in the case contacted me in 2019 about writing a book. Initially, we worked on it together, but later she decided to have a man write it. I didn’t want the book to just be about Janice’s murder and I didn’t trust a man to write her story. That’s why I had to write my own book about our friendship, our experiences as female soldiers, what led to her murder, and the process of healing from the trauma through the writing of the book.

Tell us a bit about your friend Janice. How did you first meet? What drew you to each other? What did you admire about her?

Janice and I were roommates in Seoul, Korea, where we were among a small minority of female soldiers in the military. We bonded over our common experiences and interests. Janice was 19 and I was 21 when we met. She looked up to me like a big sister. We felt comfortable sharing everything with each other, which we continued to do in letters after my tour ended in Korea, until we reunited a year later. We moved to the Washington D.C. area together, where we supported each other in facing the challenges of school, work, continuing our military careers, and dating.

What challenges did you face when writing about something so personal?

This was an extremely hard book to write. It was challenging to relive the experiences I wrote about from this time in my life. Also, I learned disturbing details while researching the book that I didn’t know at the time. Writing about the roles that others played in the story was difficult, as well. I had a lot of fear about exposing the personal details in the book. The personal and professional support and feedback I received helped me get through it. In the end, I believe everything I wrote about in the book was necessary to tell the story.

You describe the period in which the book is set as ‘a time of rapid social change’ in America. How did this manifest itself for you personally?

Janice and I joined the Army in 1976. The Vietnam War had just ended. Women were beginning to explore careers in non-traditional fields, such as the military. The sexual revolution was redefining the roles women could play beyond marriage and motherhood. Civil rights and race relations were challenging the status quo. Janice and I had to deal with sexism and racism, both of which impacted the investigation into her disappearance.

The book is subtitled ‘A True Story of Friendship, Murder, and Healing’. Can you say more about the healing aspect?

I don’t think I truly began the healing process until I started writing the book. I had buried Janice and that time in my life deep in my subconscious. I numbed my feelings with drugs, alcohol and sex for most of my life. I tried to get clean several times, but I couldn’t be successful in the long-term because I wasn’t dealing with the underlying trauma. When the detective contacted me about writing the book, I had a reason to face my demons.

First, I went to counseling through the VA (Veterans Administration), so I could begin processing the traumatic experiences that I had to write about. Then I went to Narcotics Anonymous meetings with a willingness to commit to the program 100%. The next step was to learn about the craft of writing, in general, and memoir, in particular. I found inspiration and courage by reading many memoirs. I pursued spiritual practices, such as meditation and following spiritual teachers. I started taking better care of myself by exercising and eating better. Healing is an ongoing process for me.

What message would you like readers to take away from the book?

The biggest takeaway I would like readers to get from the book is to be careful about trusting someone too quickly. Take your time to get to know them. Look out for red flags, like they want to get serious too fast, they isolate you from your friends and family, and they make you question your own instincts. Talk to people you trust about the relationship and take their feedback seriously. Follow your gut and your intuition. There are bad people out there looking for someone to take advantage of. They can be very convincing and manipulative.

Another message is don’t be afraid to face trauma from your past. It is probably having a negative impact on your life in ways you don’t even realize. Find support to help you work through it. Writing about it can be very therapeutic, even if you don’t plan to share it with anyone.

Is this the end of your writing journey – or just the beginning?

I hope it is the beginning. I have always wanted to be a writer. I did have a couple of articles published in genealogy journals. I want to write more of those. I’m also considering writing another book about my family history.

Thank you, Eva, for sharing your writing journey with us.

I’m listening to the audiobook of The Mirror & the Light, I’m reading a book from my NetGalley shelf and the next book on my 20 Books of Summer 2025 list.

The Mirror & the Light by Hilary Mantel (4th Estate) #20BooksOfSummer25

‘If you cannot speak truth at a beheading, when can you speak it?’

England, May 1536. Anne Boleyn is dead, decapitated in the space of a heartbeat by a hired French executioner. As her remains are bundled into oblivion, Thomas Cromwell breakfasts with the victors. The blacksmith’s son from Putney emerges from the spring’s bloodbath to continue his climb to power and wealth, while his formidable master, Henry VIII, settles to short-lived happiness with his third queen, Jane Seymour.

Cromwell is a man with only his wits to rely on; he has no great family to back him, no private army. Despite rebellion at home, traitors plotting abroad and the threat of invasion testing Henry’s regime to breaking point, Cromwell’s robust imagination sees a new country in the mirror of the future. But can a nation, or a person, shed the past like a skin? Do the dead continually unbury themselves? What will you do, the Spanish ambassador asks Cromwell, when the king turns on you, as sooner or later he turns on everyone close to him?

The Last Apartment in Istanbul by Defne Suman (Head of Zeus via NetGalley)

I was writing to her, so that she would know me not as this old person whose joints creaked when he rose from a chair, but as the real the man who dreamt, deceived, envied, loved…

Pericles Drakos has lived in the exquisite Circle Building for all of his seventy-five years. From its lofty windows, he has seen his little corner of Istanbul shift and transform. But as the area has become increasingly gentrified, Pericles has retreated into its shadowy corners. And when the pandemic hits, his isolation deepens.

But when Leyla, a sparky and beautiful thirty-something moves in, Pericles is enthralled. And when he discovers Leyla is a writer, he decides to put his own pen to paper and record his own fraught that of a Greek man subjected to the politics of oppression and intimidation in twentieth-century Turkey.

Go Set A Watchman by Harper Lee (William Heinemann) #20BooksOfSummer25

Maycomb, Alabama. Twenty-six-year-old Jean Louise Finch – ‘Scout’ – returns home from New York City to visit her aging father, Atticus. Set against the backdrop of the civil rights tensions and political turmoil that were transforming the South, Jean Louise’s homecoming turns bittersweet when she learns disturbing truths about her close-knit family, the town and the people dearest to her. Memories from her childhood flood back, and her values and assumptions are thrown into doubt.

Featuring many of the iconic characters from To Kill a MockingbirdGo Set a Watchman perfectly captures a young woman, and a world, in a painful yet necessary transition out of the illusions of the past – a journey that can be guided only by one’s conscience.

Green Ink by Stephen May (Swift Press)

David Lloyd George is at Chequers for the weekend with his mistress Frances Stevenson, fretting about the fact that his involvement in selling public honours is about to be revealed by one Victor Grayson. Victor is a bisexual hedonist and former firebrand socialist MP turned secret-service informant. Intent on rebuilding his profile as the leader of the revolutionary Left, he doesn’t know exactly how much of a hornet’s nest he’s stirred up. Doesn’t know that this is, in fact, his last day.

No one really knows what happened to Victor Grayson – he vanished one night in late September 1920, having threatened to reveal all he knew about the prime minister’s involvement in selling honours. Was he murdered by the British government? By enemies in the socialist movement (who he had betrayed in the war)? Did he fall in the Thames drunk? Did he vanish to save his own life, and become an antiques dealer in Kent? (Review to follow)

The Art of a Lie by Laura Shepherd-Robinson (Mantle via NetGalley)

That’s the trouble with stories, especially the ones you write for yourself. Sometimes you think they’ve ended, when they’ve barely begun . . .

London, 1749. Following the murder of her husband in a violent street robbery, Hannah Cole is struggling to keep her head above water. The Punchbowl and Pineapple, her confectionary shop on Piccadilly, is barely turning a profit, and her suppliers are conspiring to put her out of business. So when she learns that her husband had a large sum of money in his bank account that she knew nothing about, the surprise is extremely welcome. And when William Devereux, a friend of her late husband, tells her about a new Italian delicacy called “iced cream”, Hannah believes it might transform the fortunes of her shop.

But her husband’s unexpected windfall attracts the attention of author-turned-magistrate Henry Fielding, who suspects the money was illicitly acquired. Unless Hannah can prove otherwise, her inheritance will be confiscated. As she and Devereux work to uncover the secrets of her husband’s double life, their friendship opens Hannah to speculation and gossip, locking her into a battle of wits more devastating than anything, even her husband’s murder.
