Catriona Hoy is a science teacher and an author published by Lothian. Cassia Thomas was born and raised in London; with a pencil in one hand and a cup of tea in the other. She has always loved how illustrators are able to transport you into their own worlds, and so aspired to be able to do the same. Cassia drew (a lot) and grew (not very much) and finally did a Masters in Children's Book Illustration, at Anglia Ruskin School of Art. The course helped her realise her ambition to become a visual storyteller. Since then, she's twice been selected for the Cheltenham Illustration Awards, where her work has been exhibited alongside such artists as Shaun Tan.
