Last spring, I touched a magical locket and gained the Sight. I saw the world of mythical creatures I never knew were real. I fought against an evil fay creature known as the Shade. I saved a little girl, but the Shade has regained his power. I and my companions must defeat him once and for all — for my world, and the world of all fay creatures. The Shade wants to create an Eternal Winter, destroying all life on Earth. With some help, Fiona and I set out to stop him. Our quest led us to seek out the Perpetual Prison, the only relic powerful enough to trap the Shade. If we could find it, we would have the power to seal him away — permanently. However, the Shade was one step ahead of us. His lieutenant, the Dark Huntsman, galloped across forests, pillaging homes and ravaging trees, leaving everything dead. And now he was coming for us.
