Marvellous Submarine Marvellous Submarine 1

This is a new book. Condition: Brand New.

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.
