Bad Luck Girl — Sarah Zettel

After rescuing her parents from the Seelie king at Hearst Castle, Callie is caught up in the war between the fairies of the Midnight Throne and the Sunlit Kingdoms. By accident, she discovers that fairies aren't the only magical creatures in the world. There's also Halfers, misfits that are half fairy and half other--laced with strange magic and big-city attitude. As the war heats up, Callie's world falls apart. And even though she's the child of prophecy, she doubts she can save the Halfers, her people, her family, and Jack, let alone herself. The fairies all say Callie is the Bad Luck Girl, and she's starting to believe them.
