It's probably trendy right now, but I have recently read The Curious Incident of the Dog in the Night-Time, and I really liked it. Aside from having a cutout of a dog on the front cover which M.M. loved ("It has a hole in it!! [giggle giggle]". It's a library book and I hope she doesn't destroy it before I return it), it is really moving and affecting without being trite or overdone. It's wonderful how he generates empathy for an autistic narrator who is unable to feel it for anyone else.
Here is a link to Terry Gross's interview with the author on Fresh Air.
