Binding Blood by Daniel De Lorne

The groundbreaking romantic horror trilogy, Bonds of Blood, comes to a thrilling conclusion with a story of loss, grief, and redemption.

Monsters don't get to be heroes…

Betrayed by his brother and imprisoned in his sister's dungeon, Olivier d'Arjou isn't about to let a few chains get in his way. A vampire for six hundred years and a plague on his family for longer, he has no reason to hold back from wiping out the last of his family members and anyone who gets in his way. But first, he'll need to break free.

When Oberon North, witch and survivor of one of Olivier's most heinous crimes, comes seeking vengeance, it should be child's play to bend the witch to his will. But Oberon comes with more power and resilience than Olivier expects and forces him to confront truths he'd rather avoid. 

But Olivier's inner conflict must take a backseat when he learns of his sister Aurelia's plan to save the world from the demon Xadrak. A battle generations in the making, to succeed requires the ultimate sacrifice from both Olivier and his brother Thierry – and the last chance Olivier has to reclaim his humanity and a future he never thought possible.
