We Were Liars by e. Lockhart 

#1 NEW YORK TIMES BESTSELLER A modern, sophisticated suspense novel from National Book Award finalist, and Printz Award honoree E. Lockhart.

A psychological thriller about a wealthy family who spends their summers on a private island (like Nantucket). The book focuses on the consequences of one's mistakes. 

"Lockhart has created a mystery with an ending most readers won’t see coming, one so horrific it will prompt some to return immediately to page one to figure out how they missed it. At the center of it is a girl who learns the hardest way of all what family means, and what it means to lose the one that really mattered to you." —Publishers Weekly, starred review (Thriller/Mystery)
