The edge-of-your-seat, monstrously-exciting, laugh-out-loud adventures of the most unfortunate monster-hunter ever to don armour… continue.

Things can’t get any worse. Legends are running riot. Half-hunters are out of control. Darkmouth has been taken away from Finn and Emmie, and Finn’s dad Hugo – proud Legend Hunter – is washing dogs for a living.

But something even more terrifying lurks beneath the surface: an ancient horror threatening both our world and the Infested Side.

So scratch that. Things can get worse. Much worse.

More than ever, Darkmouth is going to need a hero…

Sadly, all it’s got is Finn.
