Chloe King is a smart, slightly offbeat teenager who lives a normal life (or as close to normal as a teen can get) with her single mother ... until her 16th birthday, when her life takes a weird turn. That is when she starts developing heightened abilities and learns about her ancestry. Chloe discovers that she is part of an ancient race called the Mai, whose people have been hunted by human assassins for millennia. And Chloe may be the race's sole hope for survival. Her best friends, Amy and Paul, remain by her side as she becomes overwhelmed by what she learns about her newfound abilities. Two of Chloe's classmates, Alek and Jasmine, reveal to her that they are also descendants of the Mai and may be her best protection from the mysterious figure pursuing her. But Chloe's biggest problem may be trying to decide how, or if, she should tell her mom about what's going on.
