Fangs & Felons by V.A. Dold

Bullets are flying, and Sheena Savoy is running out of places to hide. In the wrong place at the wrong time, her boss wants her silenced—permanently.
Xander Beck, a vampire with the League of Guardians, is on a mission to rescue a witch in trouble with the mob. What he expected to be a routine mission quickly becomes anything but. How can he protect the blasted witch if he can’t catch up to her?
On the run from the mob and dogged every step of the way by a shadowy group of men they can’t seem to shake, Marshal Benoit is running out of options. Come hell or high water, he will get his witness to safety.
There’s a mole at WITSEC, and as far as Sheena knows, the only person standing between her and a bullet is a Marshal she met only days ago. That is until she comes face to face with Xander and things become exponentially more dangerous as they make a mad dash for the Le Beau Ranch. She prays she will find safety there.
