The Zero Dog War — Keith Melton

The first bullet is always free. After that, you gotta pay.

Zero Dog Missions, Book 1

After accidentally blowing up both a client facility and a cushy city contract in the same day, pyromancer and mercenary captain Andrea Walker is scrambling to save her Zero Dogs. A team including (but not limited to) a sexually repressed succubus, a werewolf with a thing for health food, a sarcastic tank driver/aspiring romance novelist, a three-hundred-pound calico cat, and a massive demon who really loves to blow stuff up.

With the bankruptcy vultures circling, Homeland Security throws her a high-paying, short-term contract even the Zero Dogs can't screw up: destroy a capitalist necromancer bent on dominating the gelatin industry with an all-zombie workforce. The catch? She has to take on Special Forces Captain Jake Sanders, a man who threatens both the existence of the team and Andrea's deliberate avoidance of romantic entanglements.

As Andrea strains to hold her dysfunctional team together long enough to derail the corporate zombie apocalypse, the prospect of getting her heart run over by a tank tread is the least of her worries. The government never does anything without an ulterior motive. Jake could be the key to success...or just another bad day at the office for the Zeroes.
