I recently saw a positive review of Laura Hillenbrand's new book and it made me think of Seabiscuit. I read it and enjoyed it, but can't remember if it had any sex. Anybody happen to know? It's not typically something you find in the Amazon reviews!
I vaguely recall there is a scene where there were prostitutes but the rest of the book was okay.
What are your son's interests?
If he likes animals the James Herriot All Creatures Great and Small books are good. Sherlock Holmes has light death but isn't gruesome at all.
