It has all the ingredients that have made this such an exciting series to read - great characters putting their lives on the line for the greater good, tight plotting, great action scenes, realistic dialogue and as much tension as any best-selling adult thriller

Plenty of twists and turns in this suspense filled story with so many heart stopping moments there is hardly time to draw breath between them. Full of atmosphere and so vividly told you feel you share the friends' danger . . . Unputdownable

This is exactly the sort of book to appeal to an 11-year-old child who loves a nail-biting adventure and is interested in how the French Resistance operated in World War 2. Highly recommended

The lovingly designed jacket and hardback cover, with its slightly mottled paper and "worn" spine, evokes memories of Mervyn Peake's Letters from a Lost Uncle

A beautifully tender and enchanting story of a developing friendship between two most unlikely characters, in the most improbable of settings

A riveting tale that will capture both children and adults through its quirky storytelling

A gentle funny little book in which the story, tone, illustrations and even cover are so perfectly attuned to each other, and to the children for whom it is intended

Reminds you of The Life Of Pi, with better jokes

Dave Shelton’s debut novel, is written in a simple, direct style with affectionate drawings . . . A whimsical journey that is truly about life, friendship, and self-discovery

With wonderful illustrations this funny and charming story of a developing friendship is a heart-warming joy

Dave Shelton, a graphic artist, miraculously paints pictures in the reader's head, using words like brushstrokes

This comic skit on maritime survival stories is a book-long joke which will amuse and entertain many young readers

I recommend it to children aged 4-12 as it is an easy read, but can touch the hearts of older children too. ... The illustrations, which are drawn by the author, Dave Shelton, are perfected perfect.

This book is absolutely hilarious.. and more. A metaphor for the ups and downs of life, this brilliantly realised novel will leave readers grinning and thinking simultaneously.

A laugh on every page. Shelton is exceptionally talented ... Funny and philosophical this book will charm every reader.

It’s a really exciting book to own. A book as an object. A book as treasure ... I can sell that beautiful little blue book over and over again because it inspires wonder in me and in the children I show it to.

Entirely unpredictable. It’s an indescribable mix of fable, friendship, trust, adventure; odd, innocent, and quite wonderful.

[re: The Guardian Children's Fiction Prize] This is the book I am most curious to hear children talk about.
