One moment he had just read the strangest book he had ever come across, the next he was stumbling into the world of that same book. 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.

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.
