Isabel Otter is a children's book editor and writer. She grew up in rural Herefordshire and spent much of her childhood in trees. Isabel loves weaving stories and writing about the world around her. She currently lives in London.

Ana Sender was born in Terrassa, Spain in the summer of 1978. As a child she loved to draw, write and imagine all kinds of stories. Then she grew up (although just a little bit) and studied painting and illustration in Massana art school in Barcelona. Ana's work has appeared in newspapers, books and also fashion (she's been a pattern designer for the Spanish brand La Casita de Wendy). Her dreams have always played an important role in her work; she lives a second life there that she tries to remember when she wakes up. She likes werewolves, surrealism, and swampy places.
