Sister

I read a compelling review for Sister in the
NY Times book review section. It's written by British author Rosamund Lupton and was apparently quite popular in England last year.

It's a story of a woman who's sister is killed (not a spoiler, happens right away) so she goes to London to find out what happened. Told mostly in 2nd person, Sister is like a letter to the dead sister, a chronology of the events told by the living.

It's a good mystery novel and really wrapped me in - Lupton does some interesting things with the narrative and the POV and writes skillfully.
