Tiffany Donovan vs the Cookie Elves of Destruction [PDF ebook] 

Tiffany Donovan has a lot of responsibility as class prefect not the least of which is the annual cake sale. When she finds a new bakery to buy biscuits from, she is thrilled with how much the people of the school and the town seem to love them. But as is always the case in Devil’s Pass, the biscuits aren’t what they seem. Soon anyone who has eaten the biscuits seems to be in danger of being eaten themselves, and Tiffany has to get her friends together to save the town once again.
