SOUNDTRACK
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.
“J.T. Ellison is a rock star of psychological thrillers, and You Know Why proves it. A propulsive, first-rate thriller about sibling rivalry, sisterly devotion, and the secrets we keep to protect the ones we love. With a missing husband, a decade-old murder, and twist after twist after twist, the suspense never lets up. Fasten your seatbelt and prepare for takeoff because Ellison is at the top of her game.”
—Alex Finlay, bestselling author of Parents Weekend
“Part Hitchcock, part travel thriller, part domestic suspense, and altogether irresistible—a novel smart enough to yank the rug out from beneath you over and over, and so addictive that you keep getting back up. But don't trust that title, or anything else: you don't know why, you won't guess who, and you can't imagine what’s really going on. Man, this is a good one.”
–A.J. Finn, #1 New York Times bestselling author of The Woman in the Window
"Twisty, gripping, and impossible to put down, You Know Why is a masterfully crafted thriller about buried secrets, revenge, and the lies that can destroy a family."
—Jeneva Rose, #1 New York Times bestselling author of The Perfect Marriage
“The great J.T. Ellison elevates foreboding to an art form in You Know Why. The drumbeat of dread echoes through the pages and hits like a dirge, culminating in a deliciously satisfying denouement that will have you looking askance at those closest to you. How well do you really know your spouse, your neighbors, your friends? I guarantee you, not well enough.
—Tracy Clark, award-winning author of the Cass Raines series and the Det. Harriet Foster series
“Your husband vanishes at the airport, a stranger knows why, and suddenly everything you thought you knew about your marriage is a lie. You Know Why is J.T. Ellison doing what she does best—voicey, propulsive prose that pulls you right in, a plot that snaps tight with every turn, and characters so vividly drawn they feel like people you know. Correction: people you thought you knew. If The Last Thing He Told Me wrecked you, Ellison is here to finish the job. Five stars, no notes.”
—Kimberly Belle, internationally bestselling author of The Expat Affair
“In You Know Why, Ellison brilliantly weaves a razor-sharp web of intrigue, suspense, and page-turning thrills. The twists keep coming, each smarter and more shocking than the last, right up to the nail-biting final page. With fascinating characters and silky prose grounded in breathless action, You Know Why is a rollercoaster ride you’re guaranteed to love.”
—Barbara Nickless, WSJ and Amazon Charts bestselling author of A Voice in the Dark
