Grimsley Hollow is under attack again. Is Inari trying to seize the Key of Opa and take control of Grimsley Hollow or is she under the power of someone even more insidious, greedy, and evil? Siren has been kidnapped in hopes of drawing out his family and friends, especially twelve-year-old Gage, who holds the Key of Opa and all the power of Grimsley Hollow. The Daoi, a group of rogue werewolves, is enlisted to aid and abet. They would love nothing more than to sink their teeth into Siren's pack. When danger hits too close to home, Gage and his friends have no choice but to travel to Hemming Woods and confront the devil and his minions on their own turf - Dark Hollow. There is nothing stronger than the bond of friendship, nothing more enduring than the ties of family, and nothing more powerful than a boy who has discovered his own self worth and the magic that comes with believing in himself. But Gage must hurry. Siren is not the only one depending on him now. The Search for Siren is the third book in the Grimsley Hollow series.
