Sleeping with Beauty by Donna Kauffman--A high school wallflower decides to reinvent herself in time for her tenth reunion, with a little help from an almost-fairy- godmother.  Endlessly fun and diverting.

Thinner Than Thou by Kit Reed--a chilling, dystopic, futuristic look at America's obsession with weight.

Slightly Dangerous by Mary Balogh--one of the best romance authors out there.  Everything she writes is wonderful.  Honest.

Brimstone by Douglas Preston and Lincoln Child--Agent Pendergast, and spontaneous human combustion.  What's not to love?
