Joni Warren has skills few other 17-year-olds have: she can cast simple spells, heal minor injuries and see (somewhat) into the future.
In order to protect her friends from attacks by sorcerer assassins, summoned demons, and dimensional battle mages fighting for powerful mystic artifacts, Joni must use her supernatural powers at her command and risk her life training with spirit weapons called Remnants.
To find the answers she needs to survive, will she have to pay a terrible cost to use such evil magic?
