I listened to a book called Bearstone by Will Hobbs. It was OK, I guess....
It's about a boy who stays with an old man and finds a carved stone in the shape of a bear in a Native American cliff tomb! I think the main intent is that revenge is bad. I think that because when he cut down the old man's plum trees, he got to go home. Plus, he said so.
I don't really recommend this book. It put me to sleep.
