Now Mars is trapped in a fantasy world as a nobody, and the gorgeous, cruel Crown Prince who just kidnapped him thinks he's a spy. Keith Elarion's solution? Keep Mars under his personal, infuriatingly attractive supervision. Mars’s plan is simple- survive, avoid the plot, and find a way home. But the prince is nothing like the two-dimensional villain from the book. Keith is all intense green eyes and confusing, rough kindness, and he’s decided Mars is his to keep. When Mars accidentally unleashes a power he should not possess, he becomes the key to a conspiracy that runs deeper than the novel ever revealed. His meddling changes everything, accelerating a plot that was supposed to take years. To top it off, a cryptic bird-god just told Mars he's not just a lost college student. He's the son of the goddess who made this world. To save Keith, stop a divine war, and maybe finally kiss the man he falls hopelessly in love with, Mars has to do the one thing the book never planned for: he has to rewrite fate itself.
