About this ebook

With over 1 million books sold, USA Today Bestseller Dannika Dark introduces her next addictive series…

Raven Black hunts evildoers for fun, but her vigilante justice isn’t the only reason she’s hiding from the law. Half Vampire, half Mage, she’s spent years living as a rogue to stay alive. When a Russian Shifter offers her a job in his covert organization hunting outlaws, dignity and a respectable career are finally within her grasp. The catch? Her new partner is Christian Poe - a smug, handsome Vampire whom she’d rather stake than go on a stakeout with. 

They're hot on the trail of a human killer who will stop at nothing to get what he wants. One misstep during her probationary period could jeopardize Raven’s chance at redemption, and her partner would love nothing more than to see her fail. Dark secrets, unexpected twists, and a blurred line between good and evil will keep you on the edge of your seat.

Will Raven find the courage to succeed, or will she give in to her dark nature?

Great series and another captivating book. A little bit of mystery, a little bit of sexual tension, and a lot of great characters with satire woven in. Love the characters and the story. This was one of my favorites of the series about the breed world. I hope there will be many more to come ,as they are hard to put down.

This was an absolutely amazing start to a new series. I have read all of Dannika Darks books, and have been reading her books since she put out the first book in the Mageri Series. I am hooked!

Writing this after I've finished the whole series, and it was un-put-down-able. Will definitely revisit this series again.
