WHAT KIND OF A WOMAN FALLS FOR THE MAN HER SISTER LOVES?
Having turned her family's Victorian home on Maine's scenic coast into a charming inn, Meg Hazard worries about temperamental furnaces, peeling paint... and her restless younger sister, Allie. At least this summer Allie seems content to stay put, having fallen madly in love with Chicago detective Tom Wyler. Haunted by a violent shooting that ended a child's life and almost cost him his own, Tom arrived in town looking for a place to heal his injured leg and his wounded spirit.

MAYBE THE KIND WHO SUDDENLY BELIEVES IN GHOSTS.
When the gift of an exquisite dollhouse reopens a mystery from long ago, Meg is overwhelmed by the compulsion to solve it, and turns to Tom for help. And as powerless as she is to resist the otherworldly voice that is whispering to her of long-buried secrets, so, too, is she unable to stop something much more frightening to her... feelings for Tom she simply can-not let happen....
