Abi Elphinstone grew up in Scotland where she spent most of her childhood running wild across the moors, hiding in tree houses and building dens in the woods. After being coaxed out of her tree house, she studied English at Bristol University and then worked as an English teacher in Africa, Berkshire and London. She is the bestselling and multi-award shortlisted author of RUMBLESTAR (first in The Unmapped Chronicles series), SKY SONG & THE DREAMSNATCHER TRILOGY. When she's not writing Abi volunteers for Beanstalk, speaks in schools and travels the world looking for her next story. Her latest adventures include living with the Kazakh Eagle Hunters in Mongolia and dog-sledding across the Arctic.
