Sister/Rosamund Lupton/319 pgs.

Bee receives a phone call from her mother that her younger sister, Tess, has gone missing. Bee feels certain that Tess will soon reappear, because, after all, Tess is the "flighty" one. Nevertheless, Bee returns to London to await her sister's return. When Tess turns up dead, the police rule it a suicide. Bee doesn't accept this, and sets out to prove that Tess was murdered. Told in Bee's voice, this book grabs you by the throat and doesn't let go until the end--with a surprise thrown in to wrap it up. Highly recommended!
