The Raven King (The Raven Cycle, Book 4)

The quest for the Welsh king Glendower is completed, but kings aren't always what they're cracked up to be. Gansey and his friends are now desperate to change what they have come to believe is his fate-to die before the end of the year. They also have to cope with the villainous forces of greed and corruption who descend on their town, RoboBees, and a power-hungry demon. And there's that nagging curse that Blue will kiss her true love and he will die, and she's increasingly certain that Gansey is her heart's desire. Strange revelations about Blue's father and the introduction of a new student, who proves to be a stalwart and trustworthy ally, all help to build to the breathtaking climax. Beyond the imaginative storytelling, the colorful cast of characters, and the looping subplots, Stiefvater has tackled big questions about life and death, power and personal responsibility, dreams and promises, and fate and destiny.
