The Vampire Bat's Knot

Age Gap, Fated Mates, Monster Romance with Knotting

His darkness claimed her, but his venom sealed her fate.

Expert caver Sage Bloom descends into a Yucatán sinkhole. When her gear fails and a voice whispers from the dark, she realizes she’s not alone. She has trespassed into the domain of Noctys, the cavern’s ancient, bat-like guardian.
He claims her as his possession. His cold commands guide her through brutal lessons in submission, his voice a weapon as he uses her body to erase her human scent. He insists this violation is her only shield against a greater horror her presence has awakened. His monstrous anatomy is her prison and her salvation.
Trapped in his subterranean kingdom, Sage must choose: fight the monster who owns her body, or trust the guardian who protects her life. When an ancient threat rises, their violent bond is forged in battle, and his brutal claiming transforms into a dark, all-consuming passion.
