All Alethea had ever known was gymnastics, so when a car accident crippled her months before the Olympics she was forced to redefine her life. Of course she never thought super powers would be part of that definition.

Now nightly battles against the monsters that have begun appearing around her home town are taking their toll, not just on Alethea's body but her sanity.
