Autumn: the season of endings. And beginnings.

Especially for one young apprentice.

At the annual Festival of the Hunt, thirteen-year-old apprentice goblin hunter Finn MacCullen and his master, Gideon Lir, join other Tuatha De Danaan to honor their people's heritage. But Finn soon realizes that there are some who denounce his right to attend due to his half-human bloodline.

While he struggles to keep his place by his master's side, he finds himself embroiled in a decades-old grudge between Gideon and another Knight, bewildered (and beguiled) by a female apprentice with a temper as explosive as his own, and battling a pack of goblins determined to wipe out the entire camp in a surprise attack.

It's going to take some fancy knife work, the help of a female Knight with a lethal bow, and one old pick up truck to defeat the goblins and prove to his people that his blood runs true-blue Tuatha De Danaan.
