Can someone please tell me what good book for a high school student on permutation and combination?

Thank you

I think that Scott Hartshorn's book "Probability - A Beginner's Guide To Permutations And Combinations: The Classic Equations, Better Explained" does a fairly decent job in this regard but keep in mind that along the way, you must get in the spirit and learn some things at the undergraduate college level - if you're not familiar with these so far.
