The basis for the blockbuster motion picture directed by Martin Scorsese and starring Leonardo DiCaprio, Shutter Island by New York Times bestselling author Dennis Lehane is a gripping and atmospheric psychological thriller where nothing is quite what it seems. The New York Times calls Shutter Island, “Startlingly original.” The Washington Post raves, “Brilliantly conceived and executed.” A masterwork of suspense and surprise from the author of Mystic River and Gone, Baby, Gone, Shutter Island carries the reader into a nightmare world of madness, mind control, and CIA Cold War paranoia and is unlike anything you’ve ever read before.

Saw the movie first. Wish I'd read the book first. Movie is great, but the book is always better, with more dialogue and detail and your imagination.

Don't want to give anything away, so that's all I'm sayin'.
