The Callisto Chronicles Series

The vampire hunter who fell in love with her vampire roommate at university must now reckon with a dark force inside herself, in the sizzling second volume of the paranormal sapphic romance series following The Book of Blood and Roses.

None of this was supposed to happen: When vampire hunter Rebecca Charity went undercover at a vampire university on a secret mission, she wasn’t supposed to betray the hunters. And she definitely wasn’t supposed to fall in love with her roommate, the heiress to one of the most powerful vampire families. 

But Aliz has become an obsession. An addiction. One that Rebecca doesn’t want to let go.  

Aliz’s father, however, wants his daughter to take her place as the inheritor of his family’s prestige and power, and has plans for her to marry into another powerful vampire family. 

Everything seems to be conspiring to keep Aliz and Rebecca apart. But their all-consuming love keeps drawing them together. 

And Rebecca is discovering that there’s something darker in her heart than obsessive love for Aliz—a devouring force that might save or destroy her.

“Then her red eyes are on mine, gentle, deadly. . . . She takes her time, kissing my neck. . . . I pull her closer, and I say, Bite me.”

In the mists of the Scottish Highlands is a university where vampires study alongside humans.

Rebecca Charity is a vampire hunter undercover at the university, searching for the mysterious Book of Blood and Roses, a lost compendium of ways to kill vampires. If she finds it, she’ll be one step closer to avenging her parents, who were slain by those creatures of the night.

But when Rebecca arrives, she finds something unexpected: a coffin. Her new roommate is Aliz Astra, scion of one of the most powerful vampire families . . . and the most beautiful woman Rebecca has ever met.

The maddeningly gorgeous Aliz is everything that Rebecca has always hated but also everything she’s ever wanted, and now Rebecca doesn’t know if she wants to kiss or kill her.

When one moonlit night Aliz rescues her from a vampire attack, she accidentally makes Rebecca her Familiar. Now they must work together to break the curse—but as they get closer to solving the mystery, Rebecca and Aliz get closer, too.

Can a vampire hunter ever fall in love with a vampire?
