Meet ocean explorer Sandy Fin, silver-scaled diver of the deep, puzzler of puzzles and hero of a new madcap middle grade series from Martin Stewart, illustrated in black and white.
Martin Stewart made his first book using Post-It notes aged eight. His work has been shortlisted for major awards and translated into multiple languages. A native of Glasgow and former secondary school English teacher, he now lives on the west coast with his wife, two children, and a very big dog.
