The Great Five: The Legacies

My life has been as normal as it can get with having probably the two most famous demigods in the world as your parents and being you know, half demigod and half mortal. It's been that way for as long as I can remember, until now...

One day, everything shatters. Monsters are rampant, the gods are angry, all that pizazz.
Tartarus is on the verge on nonexistence.
Follow Zoe, Charlie, Callie, Tris and Sammy on their journey to save Tartarus. Weird right?
