A Darkly Beating Heart - A Bi Teen Time Traveling Thriller, where modern-day Reiko slips back to 19th Century Japan and the life of another girl, Miyu

A Darkly Beating Heart by Lindsay Smith

No one knows how to handle Reiko. She is full of hatred; all she can think about is how to best hurt herself and those people closest to her. After a failed suicide attempt at her home in Seattle, Reiko's parents send her to spend the summer with family in Japan, hoping she will learn to control her emotions. But while visiting Kuramagi, a historic village preserved to reflect the nineteenth-century Edo period, Reiko finds herself slipping backward in time into the nineteenth-century life of Miyu, a young woman even more vengeful than Reiko herself. Reiko loves escaping into Miyu's life . . . until she discovers Kuramagi's dark secret and must face down Miyu's demons as well as her own.
