"Linwood Barclay's I Will Ruin You is a page-turner that also has important things to say. You'll get your money's worth out of this one." –Stephen King

In the latest novel from New York Times bestselling author Linwood Barclay, a teacher’s act of heroism inadvertently makes him the target of a dangerous blackmailer who will stop at nothing to get what he wants.

How would you react in a life-or-death situation?

It’s a question everyone asks themselves, but few have to face in real life. English teacher Richard Boyle certainly never thought he would find himself talking down a former student intent on harming others, but when Mark LeDrew shows up at Richard’s school with a bomb strapped to his chest, Richard immediately jumps into action. Thanks to some quick thinking, he averts a major tragedy and is hailed as a hero, but not all the attention focused on him is positive.

Richard’s brief moment in the spotlight puts him in the sights of a deranged blackmailer with a score to settle. The situation rapidly spirals out of control, drawing Richard into a fraught web of salacious accusations and deadly secrets. As he tries to uncover the truth he discovers that there’s something deeply wrong in the town—something that ties together Mark, the blackmailer, and a gang of ruthless drug dealers, and Richard has landed smack in the middle of it. He’s desperate to find a way out, but everyone in his life seems to be hiding something, and trusting the wrong person could cost him everything he loves.

What price will he pay for one good deed?

Linwood Barclay is a former columnist for the Toronto Star. He is the #1 internationally bestselling author of many critically acclaimed novels, including The Accident, Never Look Away, Fear the Worst, Too Close to Home, and No Time for Goodbye. Multiple titles have been optioned for film.

"The latest thriller from Barclay asks the reader to accept a slightly out-there premise but delivers a tightly plotted, surprising novel that winds up explaining why the premise wasn’t really so out-there at all. It’s the kind of thriller Barclay does so well: a story that constantly changes direction and forces readers to reconsider their notions of what the book is actually about.
