Nice book, explaining QC at a high-school level: Terrance Rudolph "Q is for quantum".
Here is a very modern approach, that is also understandable without much mathematics:
"Bob Coecke: From quantum processes to cognition via pictures"

Do you already understand the basics?
Feynman is nice aswell, I like how he rambles. Try diving in here and backtracking as needed:

Don't forget to read it with a thick Brooklyn (long island) accent.
