What is a book that every 13-year-old boy should read?

Thirteen is a difficult age for most. It's a time of transition from childhood into early adulthood.
I'm keen for book recommendations you think a 13-year-old should read. Specific topics I'm keen to be covered, either directly or through metaphor, are:

• Confidence
• Development
• Fitness / Nutrition / Physical Health
• Mental Health
• Finance
• Ethics

But really, anything you think one could tackle at that age and benefit from having read the content.

I've specified boy, because it is a boy who I wish to pass these recommendations on to, and I think that perhaps the advice would be different for a girl.
