Midsummer Sweetheart (Heart of Montana #3)
Katy Regnery

Katrin Svenson is in danger. After leaving her home in secret, her only hope for safety seems to lie in the hands of her handsome but aloof protector, who's steeled himself against her deep blue eyes and sunny smile.
Sparks fly between the officer and the nurse, and those sparks turn to fire as Katrin melts the ice surrounding Erik’s heart. Yet a dark force, determined to tear the young lovers apart, must be vanquished before their sweet midsummer nights can turn into a sweet forever.
