BIO

SJ Poyton, also known as Sally, has been making up stories since she was a child, recording them in pictures and badly spelt wobbly words (she has dyslexia, dyscalculia, and dyspraxia). Her very first book was a comic about a bee.
​
​She has always been fascinated by animals and conservation, and grew up surrounded by fauna, as her family kept a small menagerie with everything from pigeons to iguanas. Once, she even smuggled her pet parrot, Baby, into school for a debate about deforestation, to show what was at stake when habitats are lost. Of course - she won!
​
Sally is now a writer and illustrator. In her spare time she likes to dig up Mammoths on palaeontology digs. One day, she hopes to smuggle a mammoth into a school visit - though getting it through the doors might be a challenge!
