He isn't ready for adult books yet unless it's more of an "advanced beginner" book. Actually, I did get "Chess for Dummies" out of the library for him and he has been reading it some.He's sort of in a weird spot in that his chess play is a bit more advanced than the kinds of books he can easily comprehend, I think. The reading level of some of the stuff we find tends to be a little high for him (..."but then, Black sabotages the white queen with a sudden kamikaze attack..."--that kind of thing). Also, he does not love following algebraic notation, though he CAN. I guess he just needs to practice.

I found this the other day and he has been doing some of the courses:

They're good, though he has a bit of the reading level issue again. There are these, too:

but I think he actually prefers the chess.com ones.
