This was one of the hardest CHERUB books to write. Normally I just come up with the most exciting storyline I can think of.

But with Shadow Wave I had to think about making a great ending, that would keep the fans happy.

I also wanted to bring back lots of favourite CHERUB characters like Kyle, Amy and Mr Large for one last adventure, but without making the story too complex.

Hopefully I've pulled it off!
