Brooke's life could be measured in blood. The blood of her patients in the ER. The blood of her comatose mother, whom she's desperately trying to awaken. And the blood in the bags she frequently delivers from storage to those who need it. When she's attacked by supernatural raiders in the storage room one night, and rescued by a sexy stranger equally as inhuman, she realizes how precious a commodity blood truly is—especially hers.

After the mysterious disappearance of the raiders and her rescuer, Brooke begins to doubt her sanity. But when the same handsome rogue saves her from a second attack, she demands answers. Liam says he's a vampire, and he's protecting her from the vampire blood cartel who discovered during the raid that she's a Fount, a human with highly addictive blood. Together they go on the run, stoking the fire between them that sparked when he first saved her.

But vampires aren't the only ones who want Brooke for her blood. There are other creatures with far more devious intentions. Will Brooke become a blood cow for the vampire cartel, or be forced into an ancient fae fox hunt? Or can the sprouting love between her and Liam save them both?
