Summary:
Eve is chosen to head the planning committee for Salem U's Founder's Day festival, which will take place under a full moon. Friends say a full moon means trouble. And trouble is just what Eve gets. (fantasticfiction.co.uk)
Dun dun dun! God, I love it. You don't see too much scary stuff in YA centering about a full moon and the bat shittiness it can spawn. I'd read it just to see what Hoh does with it. I'm sure it'd be cheesetastic!
