Reviews

ASHLEY ELSTON, author of FIRST LIE WINS
A family vacation takes a deadly turn and will have you questioning everything and everyone in this chilling, fast-paced thriller. Wickedly smart and incredibly twisted, It's Not Her hooked me from the start and never let go! You will not be able to put this one down!
JENEVA ROSE, author of THE PERFECT MARRIAGE
A gripping thrill ride with razor sharp tension and a whiplash ending I never saw coming. Kubica is a masterful storyteller!
MEGAN MIRANDA, author of THE LAST HOUSE GUEST
Compulsively readable and impossible to put down, this book starts with a bang and doesn't let up. It's Not Her is both a terrifying, twisting thriller, and a glimpse into the heart of a family both before and after a tragedy. Mary Kubica is an absolute master of suspense!
SHARI LAPENA, author of THE COUPLE NEXT DOOR
A family vacation turns unspeakably grim. I relished every page. Tantalizing, terrifying and all too real. I couldn't put it down
CHRIS WHITAKER, author of ALL THE COLOURS OF THE DARK
Twisting. Chilling. Heartbreaking. Mary Kubica is the master of misdirection, and It's Not Her is the kind of killer thriller that keeps you guessing until the final page. Cancel your plans, you won't be able to put this one down
