Finn Finnegan: Gideon's Spear (Series #2) (Paperback)

For Finn MacCullen, it's time to Irish up. When a power-crazed sorceress and the neighborhood pack of beast-like goblins team up and threaten both his master and his friends, thirteen-year-old Finn (not Finnegan) MacCullen does the only thing an apprentice monster hunter can do: he takes the fight to the enemy. And woe to the foe he meets along the way.
