Caspia Chastain, art student and barista, is gifted (or plagued, if you ask her) with the ability to draw the future, usually at the worst possible times. Her parents are four years dead; everyday she watches her brother Logan fight his cancer diagnosis. Things get worse for Caspia the day she draws an angry stranger framed by planes of light and violent, bloody images. That exact same stranger walks up to her out of nowhere mere hours later knowing things he shouldn't, like her name, her brother's illness, and her strange ability. That's when Caspia discovers her hometown is a refuge for supernatural beings both Light and Dark, and she and her brother find themselves caught up in a war between the two that predates their very birth. In order to protect herself and her brother, she turns to the one who seems to have started it all: the man who walked out of her sketchbook calling himself Ethan.

But Ethan has his own agenda, Logan's getting sicker fast, and Caspia finds that drawing the future isn't the only strange thing she can do. Meanwhile, someone really wants all of them dead. In a town where Dark doesn't equal Evil and Light isn't always Good, Caspia and Ethan find themselves making strange alliances and even stranger sacrifices in order to protect those they love.
