Alex Frith has been writing Usborne books since 2005. His diverse output covers such titles as 'See inside Your Head', 'Stories of Thor' and 'Politics for Beginners'. He has spoken at multiple festivals about his book '100 Things to Know About Space'. Alex can be found in London.

Since joining Usborne, Minna has written books on everything from pirates and gladiators to jungles and oceans. She studied Maths and Philosophy at university and previously worked as a journalist and illustrator in London, Bogota and New York. In her spare time, she loves writing stories, drawing and playing the guitar.

Matthew writes books for Usborne about all sorts of subjects, including history, science and Planet Earth. Before he did this, he studied English at university and worked for the BBC where he made funny radio programmes. In his spare time he likes to ride his bike, visit all kinds of museums and read on his sofa as much as possible.

Jonathan has fond memories of eating biscuits and reading Usborne books in his grandmother's cosiest armchair as a child, so it was only natural to end up eating biscuits and writing Usborne books as a grown-up. He studied Russian at university and his favourite topics to write about are history and geography, but he'll happily tackle any subject that might give him an edge in the next pub quiz.
