Chae Strathie is an award-winning children's author and journalist who grew up in a tiny village surrounded by a forest in Scotland, which probably explains a lot. His first attempt at professional writing was creating a Star Wars comic at the age of seven.

He sold two copies and made a total of four pence. A regular at major book festivals, Chae has toured the length and breadth of the UK and visited schools as far afield as Romania, reading his stories, acting the goat and singing silly songs about worm ice cream and beard-growing.

He lives by the sea in Fife with his wife, three annoying cats and a very old goldfish called Lazarus.

Nicola O'Byrne was born in Swaziland, grew up in Singapore and has lived in Papua New Guinea, Kenya, Edinburgh, London and Cambridge. She now lives in sunny Los Angeles with her husband, Sjoerd, and their invisible dog, Chewbacca.

In her spare time she enjoys weightlifting and baking. In 2014 her picture book Open Very Carefully won the Waterstone's Children's Book Prize, the Stockport Children's Book Prize and the Oldham's Brilliant Book Award, was highly commended for the UKLA Book Award and shortlisted for Oscar's First Book Prize and the Sheffield Children's Book Award.
