I found We Were Liars to be overly angsty and predictable. A young girl has lost her memory due to some trauma relating to her summer holiday's on her posh family's personal island. She finally returns to the island, and her memories start to return. Sad, disturbing things happened, but the foreshadowing is heavy making the mystery easy to unravel. 
 I really didn't like the lapse into poetic prose. Also, the whole upper crust debate over family inheritance seems more like a mythic American culture to me -- though I feel I've read so many inheritance drama stories in the past year or so. I couldn't relate to or care about any of the characters. (view spoiler)[And dog death! (hide spoiler)]
