Amnesia

After the murder of her parents, 17 year old girl Toni Matthews lives with the family of her best friend, Axel Creed. But their beloved city is where you'd least expect it. Underground. Why? No one seems to remember but the population is low on resources and the only other place to go is up. Every month two young adults are sent to the surface to retrieve the resources the colony needs to survive, but something's not right and only Toni and Axel seem to realize it. Between a suspicious council that runs the city and a mysterious apocalypse no one seems to remember, the pair have some answers to find.
