Wicked hour - Chloe Neill

Vampires were made, not born, until Elisa Sullivan came along. The only vampire child in existence, she grew up with a heavy legacy, and she thought she could flee her past. But then trouble came for Chicago, and Elisa came home. Alongside shifter Connor Keene, the only son of North American Central Pack Apex Gabriel Keene, she faced down a great evil and accepted her true self.

Months after the deadly attacks, while tempers are still cooling, Elisa is surprised when Connor invites her to a Pack initiation in the north woods of Minnesota, and by the warm welcome she receives from Connor's family--even though she's a vampire. But the peace doesn't last; the initiation celebration turns to chaos when a mangled body is deposited at the Pack's home. Elisa and Connor find themselves in the middle of a shifter fight, and the stakes get even higher when Elisa makes a vampire in the middle of Pack territory. Now Elisa's life, the Pack, and its vampire alliance are at risk.
