Saint X

A teenager is killed during a family vacation, and years later, her sister has a chance encounter with the prime suspect.  This book claims itself a mystery, but the whodunit is just there as a way to encounter these many characters and perspectives, and see the lives they live both before the tragedy, and the years after.  While the actual plot points are a bit cliched, they are written and explored well, though the middle of the book becomes a bit too slow.  Still, an overall enjoyable read.
