Tanya Rosie studied English Literature in Nottingham, Vancouver and London, before becoming an editor, author and passionate reader of children's books. She currently works as a commissioning editor at Walker Books, and also loves to write poems and picture books of her own. Mum, Me and the Mulberry Tree is her debut. Tanya grew up in Milton Keynes in a household filled with Iranian traditions (from her mum), and a few Scottish ones, too (from her dad). In all her writing, she likes to capture something of the way it was being a child. Find her on Twitter as @tanya_rosie.
