You Know Why - by J T Ellison (Hardcover)

Book Synopsis

From New York Times bestselling author J.T. Ellison comes a suspenseful domestic thriller about identity, revenge, and the dangerous secrets kept hidden from the ones we love most.

It's the holidays, and photographer Brooklyn Locke is bound for Italy with her husband, Trey, and their two children. But when Trey vanishes from the airport, missing their connecting flight, their impromptu vacation--and life as she knows it--begins to unravel.

Desperate to find her husband, Brooklyn accepts help from a stranger on the same flight, Eden Barrow. But Eden soon makes a shocking claim. She is the sister of Trey's first wife, and ten years ago he was the main suspect in her murder.

Struggling to comprehend these accusations, fate delivers one more blow: a violent accident that leaves Brooklyn fighting for her life. With nowhere else to turn, Brooklyn leans on Eden for support. But each kindness feels too rehearsed, feeding her doubts about Eden's motives and Trey's true past.

Brooklyn has her own dark history she'd rather forget and confronts an unsettling possibility. Her life is not what it seems, and the truth is a trap--laid by someone waiting for the perfect time to strike.
