When Helen Honeycutt falls in love with Emmet Justice, a charismatic television journalist who has recently lost his wife in a tragic accident, their sudden marriage creates a rift between her new husband and his oldest friends, who resent Helen's intrusion into their tightly knit circle. Hoping to mend fences, the newlyweds join the group for a summer at his late wife's family home in the beautiful Blue Ridge Mountains. Helen soon falls under the spell not only of the little mountain town and its inhabitants, but also of Moonrise, her predecessor's Victorian mansion, named for its unique but now sadly neglected nocturnal gardens. But the harder Helen tries to fit in, the more obvious it is that she will never measure up to the woman she replaced.

Someone is clearly determined to drive her away, but who wants her gone, and why? As Emmet grows more remote, Helen reaches out to the others in the group, only to find that she can't trust anyone. When she stumbles on the secret behind her predecessor's untimely death, Helen must decide if she can ever trust--or love--again.
