Wicked Good Time by Diana Tremain Braund

As a cop, she was trained to take control of every situation. As a woman, she couldn't control her runaway heart.

Fleeing her painful past, Christina Reynolds hopes to find peace by moving to an isolated house in rural Maine. But the solitude she sought so desperately is soon disturbed by suspicious noises, crank calls, and signs of trespassing. When the local police write the incidents off as products of an overactive female imagination, the distraught Christina turns to Forest Ranger Miki Jamieson for help.

The first woman in her agency to make sergeant, Miki is unmatched when it comes to tracking poachers and dealing with the dangers of life in the wilderness. But dangers of the heart are another matter, for beneath Miki's six-foot tall, rugged exterior is a shy, sensitive women who has opened up to few people- and trusts even fewer. As the threats escalate, the frightened Christina seeks the safe refuge of Mikie's arms. But does Christina only need her as a protector... or want her as a lover?
