Nocturnal Farm by Villimey Mist

Leia Walker has been training to protect her family from vampires ever since her best friend died six months ago. That humans are disappearing all over Europe is a distant worry—

Until her little brother goes to Amsterdam, meets a Sangue—a vampire familiar—and disappears.

Leia knows she can’t save him alone. To bring him home, she must take up arms with the Owls, a group of vampire hunters, without her vampire protectors or the Owls becoming aware of each other.

Under Amsterdam’s streets, she discovers dark secrets, a vampire who is immune to sunlight, and a threat that turns humankind and vampires alike into feral killers.

Can Leia hold on to her belief that everybody can be saved while she fights to bring her brother home—

Or will she end up as a human blood bag on the farms?
