Let It Snow (Heron's Landing #3.5)
Iris Morland

As a police officer, Matt has lived his life with one thing in mind: honor. When he discovers a beautiful woman stranded on the side of the road on his way home from work, his honor demands that he help her. But that doesn’t stop him from wanting her, especially when they lose power and must share body heat to survive the dark, snowy night. With her body curled against his, he’s torn between desire and his own seemingly unshakeable honor.
As the morning dawns, Holly and Matt are aware of a connection neither of them expected. But as old enemies rear their ugly heads, their bond will be tested as they both discover that there is no greater force than love itself.
