Woman Without a Past — Phyllis A. Whitney

She had a past she never knew and a future barred by strange and powerful secrets...

A strange sense of foreboding warned me not to relax my guard - that every shadow might be haunted ....

Successful author Molly Hunt, the adopted daughter of Long Island parents, is stunned when a handsome man she meets in her publisher's office makes a startling declaration: he is about to marry her twin sister. Molly soon discovers that she is actually the long-lost child of the wealthy Mountfort family of Charleston, South Carolina. Eager to solve the puzzle of her birth, Molly begins a fateful journey south.

At the historic family plantation, she meets her beautiful and fragile twin, Ameba, their reclusive mother, and a cast of intriguing yet disturbing characters who both question her identity and, in their way, confirm it. For her arrival has set in motion a series of strange and frightening events. In the intoxicating magnolia-scented world of her original family, haunting memories of an unsolved murder threaten the family's very existence... as well as her own.
