A full moon on Halloween means magic and mayhem are sure to follow.

Erin Hawkins is a JAG agent with the jaguar shifters police force and she's all set to attend the shifters' Halloween party as a sexy witch, the first time she's not been on a mission in three years. Between the full moon's appearance and it being Halloween, havoc and magic prevail when she and a musketeer, an off-duty cop with the human police force and jaguar shifter, Bryce Jenkins, helps her thwart a bank robbery in progress. He wins her over with his sword-wielding antics, until she realizes he broke up her brother and his girlfriend's relationship the previous year.

Bryce has wanted to take out Erin ever since he saw her in jaguar training, but he's not sure she'd be interested in someone who doesn't work for the jaguar policing force. Still, he's determined to show her a good time and give him a chance and to straighten out a matter about him and her brother's former girlfriend.

From home invasions to bank robberies, have they got what it takes to watch each other's backs, eliminate the bad guys, and have fun too? They will, if it doesn't kill them first!
