WE WERE LIARS by E. LOCKHART

A beautiful and distinguished family.
A private island.
A brilliant, damaged girl; a passionate, political boy.
A group of four friends—the Liars—whose friendship turns destructive.
A revolution. An accident. A secret.
Lies upon lies.
True love.
The truth.

Read it.
And if anyone asks you how it ends, just LIE.
