Hidden World - Water Painting Dinosaurs

Matilda Martin is the pen name of children's book author and editor Gemma Cooper. Gemma has always had a love of learning new facts and finding out how things work. A keen fossil hunter, Gemma loves writing stories and discovering new ways to write about the world we live in. Her books are published internationally, with many titles becoming best-sellers and firm favourites on children's bookshelves. Awards as a book editor include the 2025 Trade Children's Trade 0-8 Years award for 'Magic Searchlight Seek & Find Ocean Animals', and in 2023, Gemma won the BookTrust Storytime Prize as author for, 'Can You Tickle a Tiger?'. Teresa Bellon was born in Albacete, Spain in 1987. She has illustrated books for Spanish and international clients and her work has been shown at several exhibitions. Her influences are mainly Portuguese and Nordic illustrators of children's books and Teresa's own drawings have a reduced colour palette with simple compositions. Finally, Teresa finds inspiration wherever she can. So she travels, buys illustrated books and walks around her home city, Madrid.

Gemini Books are the creators of the bestselling Magic Water Colouring and Scratch and Draw series.
