Roary Rex is a small T Rex with a very big roar, who especially loves to be naughty. However on this particular day it's not until his own naughtiness gets him lost that he finds his full potential.

In this book we meet Roary and his family, Mummy, Daddy and baby sister Rex. As well as his other dinosaur friends, Edmonto and Gorgo Saurus, who don't mind his jokes as much as their very serious neighbour Tetchy Triceratops.

The inspiration for this book comes from a mountanous area of Valencia, where we go every summer. I have based a lot of the illustrations on paintings I did of the scenery there. The dramatic landscape, of huge rocks, underwater pools and hidden caves, have always made me think of prehistoric times. At bedtime when we didn't have good light to read by, my children asked me to make up stories, and Roary Rex was one of them.
