What You Don't Know (Thorndike Press Large Print Core Series) - Hardcover

"One of the most well-written thrillers I've ever read."
--BookRiot

"Addicting...a rich, character-driven story...leaves the reader affected long after the last page is turned."
--Mystery Scene

"Gritty...What You Don't Know takes readers to some crawlspace-creepy places."
--Colorado Springs Gazette

"Outstanding dark debut...it paints an absorbing, graphic portrait of the dangers of getting too close to evil, and is breathtaking from the first page to the last."
--Daily Mail

"Superb characters, sparkling dialogue, and a gripping, terrifying plot, plus flashes of humor to boot; this book has it all. It's very hard to believe this is Ms. Chaney's first novel."
--Chris Pavone, New York Times bestselling author of The Travelers

"JoAnn Chaney's book, mysterious with all that is concealed and undeclared, compels the reader to acknowledge that things are not as simple as we like to believe, and to recognize that evil does not always lay outside of us, but deep within us. Chaney's psychological insights and social perceptions are infallible--brutal, indignant, and full of surprise."
--Susanna Moore, bestselling author of Paradise of the Pacific

"In What You Don't Know, JoAnn Chaney beautifully analyzes the effect a monster can have on those in their orbit and how, in the need to catch one, so much is revealed about the monsters we hide in ourselves. A masterclass in character study, a beautifully woven story, and truly chilling at its core, this is a literary crime novel not to be missed!"
--Sarah Pinborough, bestselling author of Behind Her Eyes

"Crisp, dark, brutal and worth every nightmare it gave me. Chaney's serial killer is chilling, her characters are humanly flawed, and her story is intense which creates the perfect recipe for a page-turner."
--BookRiot

"A taut thriller...Richly drawn and vividly imagined characters...Tense, compelling greatness. Chaney is an author to watch."
--Library Journal

"Unusually thoughtful...Relies more on character studies than gory details...It's the escalating psychological tension and the interactions of three-dimensional characters that lift this well above the serial-killer norm."
--Kirkus

"Well-drawn characters...a thrilling read in the tradition of Jeffery Deaver's The Bone Collector."
--Booklist

"Unsettling, well-crafted...All of the point-of-view characters are tragically flawed in believable ways."

--RT Book Reviews

"A careful study in characters and deception...I read this book with my breath held and the lights on."
