She'll fall in love again...with a man and the island. Charlotte returns to her Aunt Bess and Mackinac Island, a quaint retreat that welcomes summer tourists and allows no cars, to renew herself and write about the island's ghosts.

She's come to help Bess with her heartache, an ended love with Shaun, and to renew a friendship with neighbor Hannah.

In winter Mackinac closes down and everyone looks forward to the ice bridge that freezes across the Straits of Mackinac.

Until Hannah disappears into the icy waters crossing it.

Everyone says it's an accident. But Charlotte and her admirer cop friend, Mac, don't think so. Something isn't right. Hannah was too smart to go off the path.

So it's murder...but why...how...by whom?

In the end, it's Mac–and perhaps Hannah's ghost–who saves Charlotte and Bess's lives when the killer decides they're too close to the truth and tries to kill them, too.
