Billy Kool was an ordinary boy until he was thrust into the life of an extreme sports TV celebrity.

Billy feels down that the final episode of the Xtreme World of Billy Kool is coming up. But he is also excited because the final episode will feature the most extreme sport yet: rock climbing! Will Billy be able to climb the full rock face, or will he fall?

At the end of the book, there is an extreme information section detailing the origins of rock climbing, a glossary and a description of the equipment used when rock climbing.

Part of an 8-book series, the Billy Kool books are informative, empathetic and exciting; targeted to readers and reluctant readers alike ages 8-11 years.
