Spook's: Slither's Tale

Far from the Wardstone, a new darkness emerges as Slither, a haizda mage who feeds on human blood, gets drawn into a perilous journey after a local farmer's death. The farmer offers him a deal that leads to the City of the Petrified Tree and a powerful fallen star-stone, bringing Slither into contact with Grimalkin, the Witch Assassin. This series inspired the upcoming movie The Seventh Son, starring Jeff Bridges, Ben Barnes, and Julianne Moore.
