Gunner by Kim Fox

Lion shifter, Gunner, is on the worst date in the history of worst dates when he sees someone who really catches his eye. Only problem is, she’s breaking into the fire station where he lives.
Dragon shifter, Aleida, didn’t come to Colwood, Montana for love. Far from it. She came for help in stopping her powerful brothers from carrying out their devious plans. But when the help Aleida is looking for turns up empty, she has no choice but to turn to the grumpy lion shifter who seems to have taken a liking to her.
And when Aleida’s dragon shifter brother comes seeking revenge, she’s going to need all the help she can get. Luckily, the shifters of the Colwood Firehouse are always up for a good fight!
