Unhinged

She used to hunt monsters.
Now she's married to one.
 
Wren Malus never expected to fall in love with a seven-hundred-year-old vampire...especially the powerful, dangerous man she was forced to marry. But Xavier Malus has become her protector, her partner, and the one person she trusts more than anyone in the world.
 
As the city edges toward chaos and old enemies close in, Wren fights to keep vampires, werewolves, and humans from turning on each other, knowing the fragile peace depends on her.
 
But when a deadly secret threatens everything she loves, Wren must choose between the life she swore to leave behind and the man she can't bear to lose.
