The Book of Lies — Mary Horlock

Life on the tiny island of Guernsey has just become a whole lot harder for fifteen-year-old Cat Rozier. She's gone from model pupil to murderer, but she swears it's not her fault. Apparently it's all the fault of history.

A new arrival at Cat's high school in 1984, the beautiful and instantly popular Nicolette inexplicably takes Cat under her wing. The two become inseparable -- going to parties together, checking out boys, and drinking whatever liquor they can shoplift. But a perceived betrayal sends them spinning apart, and Nic responds with cruel, over-the-top retribution.

Cat's recently deceased father, Emile, dedicated his adult life to uncovering the truth about the Nazi occupation of Guernsey -- from Churchill's abandonment of the island to the stories of those who resisted -- in hopes of repairing the reputation of his older brother, Charlie. Through Emile's letters and Charlie's words -- recorded on tapes before his own death -- a "confession" takes shape, revealing the secrets deeply woven into the fabric of the island . . . and into the Rozier family story.
