Poseidon's Academy and the Final Battle (Paperback) (ISBN-13: 9780648470182)

After spending her life cursing her powers and running away from the prophecy, Hailey is finally ready to accept that she's the only one capable of defeating the Olympians. With the help of her friends and the military, Hailey enters the battle to fight for her world's freedom. But the gods aren't working alone. They have armies of nymphs, monsters, and Olympian Mysteries protecting them. Taking them down isn't going to be as easy as Hailey thought, especially when they appear to be immune to her powers. But she's willing to do whatever it takes to save her world, even if it means sacrificing her own life.
