Publisher's Synopsis
Dervla is the babysitter from hell - literally. She's very strict, she eats spiders, and … are those horns? No wonder Becky is everybody's hero when she manages to rid the neighbourhood of the demon babysitter.
Don't ask how, but hey, pssst, there are vomit-coloured stink bombs, there is an abandoned shed, there is demon-food.
You have been warned.
