The Art of Racing in the Rain by Garth Stein.
I went through a dry spell for a while where everything I picked up to read would lose my interest before I finished. This book ended that bit of ennui.
I stayed up late last night to finish reading it.
Not to give it away, you learn this in the very beginning any way, but the dog dies. I usually try to avoid books in which a dog dies. I always cry like a baby. And I did with this book, too, but sometimes a good cry is just what is needed. It's about life and love and loyalty and dreams. I give it two thumbs up.
The flat tongue and also lack of thumbs figure prominently in the story.
