A Taste of Your Own Magic by Katie Salidas

Just when newly minted ASSET agent Sage Cynwrig thought she was getting the hang of this whole magic thing, a smooth-talking Djinn named Luke moves in next door. And he's got more on his mind than making her wishes come true.

He'll have to take a number.

Between her sharp-tongued, machete wielding partner, Grey, and the flirtatious vampire-for-hire, Zack, Sage has enough magical men making her life hell. 

And then there's the new job. It's all hands on deck at ASSET. Magical creatures are dissapearing from the Las Vegas Strip. Rumor has it, the missing creatures are ingredients in a forbidden magical recipe. Someone's attempting to recreate the lost Amulet of Emmuri, and gain power to rival the gods.

Because of course Sage's first official assignment as an agent would require her to, you know, save the world! 

To accomplish that, however, she'll have to cross enemy lines and break the very magical laws she just swore to uphold.
