Tired of romances where everyone is twenty-five?

Most romantic suspense puts its heroines in their twenties or early thirties. Fatal Equation gives you Laura O'Brien — a wealthy widow in her fifties, sharp, self-sufficient, and entirely unprepared for what happens when she meets Ali Kurmi, a 35-year-old British-Indian songwriter with a troubled past of his own.

This is not a story about a woman rediscovering herself through a younger man. It is a story about two complicated adults building something real — while a ruthless enemy works quietly to destroy them both.

Set between rural Hampshire and County Tipperary, with a companion soundtrack woven into the narrative, Fatal Equation is romantic suspense for readers who want emotional depth, genuine danger, and characters who feel like people they might actually know.

What readers are saying

"What sets Fatal Equation apart is its fast-paced action, unique plot, and well-developed characters. The protagonists are a strong and intelligent woman and a man with a strong moral compass."
— JD, Amazon Review
"An intertwining tale of a love that doesn't conform to society's self-limiting rules. Add in tales of the music business and some unhinged family members and you have a love story which is just so much more than most in this genre."
— Richard, Amazon Review
"Why is this book hidden away? Much more than a romance. An enjoyable, good read with many twists and turns."
— Pam, Amazon Review
