Sweet Like Poison by Sarah McCreight

To be a Lustre is to be in tune with femininity. To be blessed by Mother Nature herself and hold gifts others can only dream about.
To be an Erebus is to be strong. To be an alpha male that will protect their mate at all costs.

Mavis never thought she would meet her Erebus. Hidden away from life, the Lustre knows very little of the outside world as the years pass by in the dark, all thanks to the Null, the man empty of magic who is supposed to be her carer.
Corvin is the strongest. The biggest. But also the most dangerous. Most Erebus are given a second soul. An animal, a strong creature.
He was given a monster. A creature he could never hope to tame — until his mating mark appears. His mate is calling the monster home and he will not disappoint.
