The Games of Enemies and Allies by K. M. Shea

At night they’re enemies. During the day they’re friends. Only one of them is aware of this…
My stress levels skyrocketed after I discovered the deadly vampire who has taken over downtown is Considine Maledictus, one of the most powerful vampires alive.
Now I’m even more reluctant to tangle with him, but he’s started showing up in the middle of my investigations, even if they’re outside his territory. I never know if he’s there to fight or to lend me some unexpected help.
I don’t have time to ponder his weird behavior, because a group of local wizards are up to some shady practices. They’ve never been fond of the non-magical, but suddenly they’re popping up all over the city, “helping” humans.
At least I can count on my vampire friend and next-door neighbor, Connor, for some laughs. Except…he’s been acting strange and is even more touchy-feely than usual these days.
Regardless, I’m going to stay focused on protecting my city. I’m just not sure if I should be more concerned about the wizards, or the chaotic vampire who swaps from friend to foe on a nightly basis.
