Ben Lerwill studied French at university but never tells French people this. He's been working as a freelance travel writer for more than a decade, which means his house is cluttered with atlases, guidebooks and ill-fitting socks he had to buy from a Serbian market after forgetting to pack any of his own. Again. His writing has appeared in more than 50 national and international publications, from The Sunday Times to National Geographic Traveller.

Ben's passions include the outdoors, music, wildlife, running and reading. He is thrilled that, through children's books, he can share his enthusiasm about the wider world with young readers. He's at his happiest when he's on a long walk and his children haven't yet pinched all the snacks.

Sandra was born in Barcelona and still lives there now. She comes from a long line of artists and studied Fine Art.

She works under the supervision of her two cats, Chicho and Rudo, and dreams of working in a studio overlooking her garden one day.
