Luca Galioto can tattoo just about any spell, but he specializes in healing tattoos. He’ll need to create his masterpiece after his mate, and Salem PD detective, Ash Montgomery brings in a human suffering a curse to end all curses. Luca uses every ounce of strength to save the man—because they both sense he’s their third.
Colby Kennedy doesn’t believe in witches, demons, fated mates, and the things that go bump in the night. Yet he struggles to ignore the deep-seated lust he feels every time he looks at Luca and Ash. No matter his need, he has his brother to care for and a business to run. He doesn’t have time for nonsense.
The demons don’t stop coming, putting everything he holds dear in jeopardy. Luca and Ash, and the coven at Enchanted Ink, are the only things keeping him and his brother from losing everything.
