Her name was Cathedra. Leave her last name blank, if you will. Where normal people would read, "And they lived happily ever after," at the end of every fairy tale story, she could see something else. Three different things. Three words: Lies, lies, lies. A picture that moves. And a plea: Please tell them the truth. All her life she dedicated herself to becoming a writer and telling the world what was being shown in that moving picture. To expose the lies in the fairy tales everyone in the world has come to know. No one believed her. No one ever did. She was branded as a liar, a freak with too much imagination, and an orphan who only told tall tales to get attention. She was shunned away by society. Loveless. Friendless. As she wrote "The End" to her novels that contained all she knew about the truth inside the fairy tale novels she wrote, she also decided to end her pathetic life and be free from all the burdens she had to bear alone. Instead of dying, she found herself blessed with a second life inside the fairy tale novels she wrote, and living the life she wished she had with the characters she considered as the only friends she had in the world she left behind. Cathedra was happy until she realized that an ominous presence lurks within her stories. One that wanted to kill her to silence the only one who knew the truth.

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. 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.
