Behemoth: The Jharro Grove Saga, Book 6 (Unabridged‪)‬

The Behemoth was created 1,000 years ago, its body stretching for miles under Malaroo's swamplands turning them into a dangerous and uninhabitable place. Now it has learned to swallow the peoples of Malaroo and transform them into its own army; a twisted mix of troll and man known as the Trollkin. It hungers to consume the power of the Jharro Grove and if it succeeds the world will be plunged into darkness.

Justan and Jhonate, forced to hold off their wedding until the threat is over, find themselves stuck between the two rival factions that are the only hope of defeating the Behemoth and its everlasting hunger.
