Vamps, wolves, and rock’n’roll!





Vamps, wolves, and rock’n’roll!

When her night off at her favorite band’s concert turns into a chilling murder investigation, ICRA Agent Gina Brent would like nothing more than to distance herself from the case.

The mere thought of keeping an eye on the delectable rockabilly singer whose fan ended up drained and dead by the backstage door triggers Gina’s flight response—except her connection to Aric Sutter is precisely why her boss believes she’s the right wolf for the job.

Of course, the man has no idea about the massive crush she’s had on the hotter-than-sin vampire for years.

Post-show chats are one thing, but spending time in the singer’s proximity beyond the safety net of a crowded afterparty threatens to take a toll on Gina's composure. Especially since she can’t shake the feeling that the alluring darkness behind the vamp’s fanged smile might be lethal for more than just her werewolf heart.

Fans. Fangs. Fallouts.

Aric Sutter is trouble. The kind of leather-wearing, smooth-talking trouble Gina doesn’t need when dealing with a case that hit way too close to home.

She’s done embarrassing herself. Done tolerating his shifty ass.

But when her gut keeps insisting the threats following the rockabilly singer around are tied to her investigation, she can’t ignore that Aric is her best shot at success.

Maybe even her only one.

Aric holds the answers. But even if Gina can break through his lies, can she truly trust someone whose past might be a whole lot bloodier than nipped necks and broken hearts?

DOWN WITH VAMPS is the thrilling continuation to the ICRA Files: Berlin series by USA Today bestselling author Gaja J. Kos, where urban fantasy meets rockstar romance!

Can you break a curse when you’re broken yourself?

Attending bloody fights seems to be the only way Gina can appease her inner wolf and feel something in this messed-up reality the supernatural war has left behind.

She’d lost too much. Including, as loath she is to admit it, herself.

When a Leshy ambushes her on a darkened street with an offer to come work for the Interspecies Crimes and Relations Agency, Gina waves him away. What good could a packless, beaten-down werewolf be?

A nearly lethal incident, however, forces her to reconsider her options.

With the foul magic infecting her brother acting up, ICRA’s resources might be the only way to save him. A good thing—if only taking the job wouldn’t mean diving headfirst into the very world Gina wanted nothing more than to disappear from. Worse yet, it would mean facing the pain she’d only managed to survive by burying it so deep down not even its ripping talons could do harm. 

To release it…

Gina wants to save her brother. She just isn’t sure if she can save herself.

Fans of kickass heroines, good old rockabilly and blues, and thrilling supernatural suspense will love exploring the shadow side of Berlin in FANG DEEP IN THE BLUES, the prequel to the exciting new series by USA Today bestselling author Gaja J. Kos!
