The Other Side of the Island by Allegra Goodman (teen). I've always enjoyed this writer's adult fiction (Intuition is one of my favorite books ever) and this was quite an enjoyable foray into teen literature.
Dreamers of the Day by Mary Doria Russell. Not a bad read, but certainly more lightweight than I've come to expect from this writer. If you really want to see what she is capable of, read The Sparrow or A Thread of Grace.
Unexpected Blessings: Finding Hope and Healing in the Face of Illness by Roxanne Black (nonfiction) -- A good read for anyone who lives with chronic illness. Black (who suffers from lupus) provides some good perspective and food for thought.
Science Fair by Dave Barry and Ridley Pearson (teen) -- a fun read that made me laugh out loud several times. It seemed to drag on a bit long, but maybe that's because I have the attention span of a gnat lately.
