Rutger by Cari Silverwood

The Ghoul Lords threaten the extermination of all humankind and much of our world has been destroyed. There will be love, death, and dirty, messy sex among the ruins.
Sex is what keeps a girl like Cyn from going insane with the blossoming light of dawn, for daylight brings the Lure.
A brutal act by Cyn tore apart the lovers and now she must make amends. She’s going to need her well-muscled beaster males to rein her in, pin her down, and make sure she shoots in the right direction.
Gather your weapons. It’s time to descend to Ground Level and find Big Daddy, the research vehicle lost during the invasion. Within must lie the truth of the Maelstrom experiment.
