Ghost Moon by Kathryn Knight

When Lark Cavanaugh’s life in New York City falls apart, she’s left reeling from a staggering betrayal. She escapes to Cape Cod, where a distant relative has left her an old house with a tragic past. Rumors of a haunting presence plague the abandoned home, but Lark doesn’t believe in ghosts…until she has no choice.
After completing his military duty, veterinarian Jesse Holt returns to his small hometown to take over his father’s practice. He soon finds himself drawn to the alluring redhead now living next door, but she has made her intentions clear—she’s moving back to the city as soon as possible. When frightening events threaten her safety, though, he can’t deny his protective instincts.
Unable to fight their feelings, they give in to desire…but another battle looms. Lark’s arrival has awakened a decades-old mystery, and the truth of what happened at Holloway House will only be revealed when it claims yet another life.
