Jake knew that a field trip to the cemetery would lead to bad things. Bad things like an angry class bully. Bad things like a mysterious tombstone. Bad things like a scratched eyeball. Most scratched eyeballs heal up in no time. They don't pop out of their sockets or float in the air or help you cheat on your math test. And they almost never go off in search of revenge. Now Jake's eyeball has a mind of its own, and it's up to Jake to find out what it's after and why. Whatever it is, it's something ancient. Something evil.
