Rhiannon Lassiter began writing when she was still at school. The first agent to see her work encouraged her to finish Hex, which was accepted when she was nineteen by the first publisher to read it (Macmillan).
Rhiannon graduated from Oxford University and has written eight best selling novels, several short stories and one non-fiction title for children and teenagers. She has edited an anthology of poetry and prose. Alongside her writing she works with her mother, the well known author Mary Hoffman, editing the children's review magazine, Armadillo.
