Percy Jackson and Annabeth Chase have survived countless monsters, gods, Titans, and finally their most difficult opponent of all--high school, though not without their fair share of mishaps and unexplained absences. All they want to do now is enjoy their summer before tackling their next adventure; college. After a series of strange encounters, however, they realize that this summer is going to be just as eventful as the rest. Meanwhile, Earth's Mightiest Heroes are fractured. Tony Stark and Steve Rogers haven't spoken in months, and even with new members, the team is suffering. They know that something is coming, but the question is; will they reconcile in time to thwart it? With the appearance of old friends, new enemies, and peculiar allies, the Avengers are forced to accept that the world is even bigger than they thought.
