The faeries are preparing for a war throughout worlds. But before the fighting comes the talking. May is approaching, but there's no way Megan O'Reilly can focus on plans for graduation and beyond when the ancient monsters called the Fomoire are about to break out of their frozen lake. As the ice melts in the Spring air, a conference of magical beings from around the world is being called. Apparently there are a lot of risks involved in properly equipping this kind of party. There are so many places--Earth, different mystic realms, the collective unconscious, an outright netherworld--to go, people to see, and things to be done. Megan is going to help. No matter how dangerous it gets.
