We stand there, screaming into each other's faces. How I hate him. How I've loved him. How I want him destroyed.

After a year of preparation, 18-year-old Raven Smith has planned out every detail of her summer vacation in Europe. Yet, while still enroute to Italy, Raven finds a letter in her carry-on suitcase that tells her not to go to Europe, that an "evil agent of Hell" is looking for her and he will find her if she disregards the letter's message.

Deciding that it was a product of insanity, Raven chooses to disregard the letter's message.

In her cross-Europe trip, Raven only wants to feed her love of art history and spend time with her older sister. She's unprepared for Andras and his strange fascination with her, not to mention the all-consuming attraction she has for him. She's definitely unprepared for Nicholas and his brothers, Stephen, Albert, and Tobias, diverting all of her plans and sweeping her off to a Swedish Castle.

But the letter was right, the agent of Hell has found her, and Raven has become a game-piece in a very dangerous game.
