Haunted Warrior by Allie Mackay

Kendra Chase is exhausted from her work as a ghost whisperer, so she’s been looking forward to her vacation in Edinburgh. But work awaits her as the tiny fishing village is being excavated, and supernatural uprisings have been reported. Graeme MacGrath knows the source of the psychic trouble. The excavation is disrupting the protective veil between this world and darker, more ancient ones. He hates to admit it but he will need the fetching Kendra and her paranormal abilities to save the town he loves from unspeakable evil.
