When librarian Sigrun falls head-over-heels for the sophisticated and very married Edgar Leyward, she never expects to find herself in his bed—or his heart. Nevertheless, when his enigmatic wife Octavia dies from a sudden illness, Sigrun finds herself caught up in a whirlwind romance worthy of the most lurid novels on her bookshelves.

Sigrun soon discovers Octavia wasn’t Edgar’s first lost love, or even his second. Three women Edgar has loved met early deaths. As she delves into her beloved’s past through a trove of discovered letters, the edges of Sigrun identity begin to disappear, fading into the women of the past. Sigrun tells herself it’s impossible for any dark magic to be at play—that the dead can’t possibly inhabit the bodies of the living—but something shadowy stalks the halls of the Leyward house and the lines between the love of the present and the obsessions of the past become increasingly blurred—and bloody.
