Ethan Evans, a Carleton University student with everything going for him, stumbles upon the mysterious body of a gravely injured young woman on campus one Hallowe'en. Given to the care of the Ottawa Police and the staff at the Montfort hospital, he thinks no more of it.
Until monsters attack him just days later.
Saved by the very same girl he found, he embarks upon a seemingly impossible quest to return the young queen to her people before the divide between worlds closes for another year. Chased by monsters and the Ottawa Police alike, the pair recruit a motley crew of unlikely friends to help them on their way.
Meanwhile, in the land of the Pobl Gwir, the idyllic island city, Y Ynys Bendigaid, and the mighty fortress, Caer Avallach, is under siege, the island lake surrounded on all sides by the frog-like men known to them as the Dynion Gors.
Desperately in need of their queen, and the Knights of Caer Avallach who followed her onto the battlefield, the people of Y Ynys Bendigaid await their champion...
... And it's not who they expected.
