Ciara had a relatively normal life. A normal mom, a normal best friend, a normal boyfriend, just boring, naive, normalcy. The only strange thing was that she didn't know her father. Until her 15th birthday. On her 15th birthday everything changes. In the post-apocalyptic city she lives in, once every five years there are four Aptum. The Aptum emerge on their 15th birthdays. They used to protect the story. Now, they are hunted. But Ciara is special. Ciara is the one who might just be powerful enough to save them all.
