The Ghost Guard - Joel Cool - Bog

Frankie Dainger didn't choose to be special. His mission was thrust upon him. He had it all figured out and running like clockwork. With his mining helmet guiding the way, and his obsidian rock necklace protecting him from the ghost trolls, what could possibly go wrong? Ultimately, the thing he fought the most wasn't at fault for what would leave him powerless and uplift four new heroes to save the town from a troll takeover. Two best buddies, the sister, and her newest high school crush risk their lives on Halloween night, the unlikely saviors of a town on the verge of battle.
