I think Problem-Solving Strategy is an interesting book for teens. It does not need a deep mathematical background. However, if its math is too hard you can find an interesting and small book about discrete mathematics¹ to read first and then switch back to this book. I read it when I was in high school and this book motivated me to do stuff in CS.

1. I think what constitutes a discrete mathematics book for teens depends on native culture and language. I know a good one in my language, but I do not know any good ones in other languages.

These are related Persian books: Alphabet of Mathematics and Computer Olympiad. Mathematics for teens by Yahya Tabesh. I couldn't find its link in the web, may be is too old. Also I'm not sure I said the name correctly, I remember it because of interesting images and its beautiful cover.

I think problem solving strategy is interesting book exactly for teens. It doesn't need deep mathematical background. However If its math is hard for startup, you can find some interesting and small discrete-mathematical book and start reading them, then switch to this book. I read it when I was in high school and this book motivate me for making stuff in CS.

P.S: I think small interesting book in discrete-mathematical area for teens, depends to country culture and its language, I know good one in my language, but I don't know any good one in other countries.
