The Lupatus Stone

The adventures of witch Jessica and witch hunter Damien continue as they race after Supai, malevolent Incan god of death, in the hope of stopping him from restoring his full power. The chase leads them to a powerful werewolf artifact hidden deep in the mountains of northern British Columbia, but the success of their mission lies in the hands of a pair of estranged siblings - one of whom is hiding a deadly secret. 

After being cursed by a werewolf seven years ago, Nathan's only means of survival has been to run and hide. Unable to forgive himself for what he's become, Nathan has done everything he can to isolate himself from the world. That is, until he comes face-to-face with Abigail, the younger sister he abandoned, and learns she's being hunted by Silas, the same werewolf who bit him. Abigail holds dangerous knowledge about the whereabouts of the mysterious Lupatus Stone, and Silas will do whatever it takes to control the artifact's power. Thrust into a world of magic he didn't know existed, Nathan faces off against dragons, giants, and Supai's army of shadow demons, all while trying to keep his identity a secret from his sister.

When his inability to control his curse puts the others in danger, Nathan must learn to embrace the wolf within or risk losing the artifact - and his last chance at family - forever.
