Bottoms Up by Candace Blevins

Book Two of the Rock Bottom Duet

When a magical necklace chooses you, surviving supernatural society becomes the least of your problems.
Silver thought learning about vampires, werewolves, and dragons was challenging enough. Then a freaking magical artifact decided to make her its new owner — and suddenly she’s caught in the crossfire of Julian’s fight for freedom.
Julian has been owned for nearly three centuries. First by an opera company, then by his vampire maker. His current owner, the local Master Vampire, devises a path to his freedom — but the price is steeper than either he or Silver could have imagined.
Silver has survived everything supernatural society could throw at her, and she’s navigated a world of fangs and claws on her own terms. But when Julian’s quest for freedom demands she participate in the trial-by-fire, she discovers that loving someone means being willing to fight battles you never saw coming.
The road to Julian’s independence demands sacrifices that will test them both. Silver must provide control far beyond anything she’s ever been asked to give. Julian must prove he can become a man worthy of freedom — and of Silver’s love — even when it means enduring punishments that push him far past his breaking point.
In a world where vampires play by different rules and demons make tempting offers, some relationships are forged in fire. Silver and Julian’s love will either emerge stronger than ever, or be destroyed along the route they are required to travel.
The hurdles seem insurmountable, but both are determined to walk this path together.

Happily ever after was never going to come easy.

Warning: Contains explicit scenes, BDSM elements, supernatural power dynamics, and the kind of love worth fighting Hell itself to claim.
