The Marvellous Submarine (The Marvellous Submarine, #1): The brand new whacky illustrated fiction book for fans of THE BAD GUYS and THE TREEHOUSE series!

In this very funny and irresistibly silly junior fiction book, The Bad Guys meet The Treehouse series, but in a brilliantly invented submarine.

Readers, be warned!This book is set on Monkey Island and contains a super-smart gorilla called Harold, two regular kids called Poppy and Billy, and the world's greatest inventor, who happens to be their mum. BUT it also features a villainous kidnapping, a secret volcano, pirates on yachts, a hungry blue whale, exploding basketballs - and a whole lot of water. Plus, there's Mum's greatest invention yet: a Marvellous Submarine.
