"Stormwood's Fury" by Rick Skowronski and E.C. Skowronski (Book 2)

Buried deep within the enchanted and ominous forest of Stormwood, the frontier village of Westpost tends its hopeful vigil, a lone candle of civilization standing against the dark and rampant evil that envelops it like a shroud. Amid the conflict, Syren and her valiant friends struggle to secure and maintain a ring of safety between the outer wall that protects the villagers, and the cruel wilderness savages that would destroy them.
But Stormwood will not be pacified.
The hard-fought and tenuous balance is disrupted when the forest erupts in an explosion of malice. A pair of tattered refugees stagger into town, followed by a mysterious stranger. Pressed by the seething hordes from outside the wall and threatened by an unspeakable horror that lurks from within, town and townsfolk find themselves again engaged in a desperate battle for survival. Can Syren overcome the panic that surrounds her, rally her company, and defeat the relentless foes that oppose them, or will the relentless evil of Stormwood sweep them aside and devour everything she holds dear?
