Unnaturals tried to kill Mason Douglas and his family. Big mistake.

He became The Butcher, a cold relentless Hunter with a vendetta that took him across the world.

And now, on his return home to Australia - to mend his heart, soul and family - his destiny collides with a millennia-old struggle between strange Gods.

Their prize is Earth. Their warriors are warring races of Unnaturals: the Bloodells and the Darkells.

As an unlikely alliance forms between Natural and Unnatural - between the Douglas clan and the Darkells - Mason's family grows in unexpected ways... not all of whom are human.

Sparks fly, lust inspires, and love ignores all the boundaries as the very definition of family changes. Prepare to push your boundaries.
