Simulacrum

Some bonds stretch across time and space--and defy even death. Kelsey and Laura make an odd pair in college-bookish and cynical, Kelsey acts the shadow to sun-bright, ever-popular Laura. But when Laura is robbed of her burgeoning dancing career by stomach cancer, Kelsey flourishes in her absence. The girls eventually drift apart. Years later, Kelsey attends Laura's funeral. Shaken by old recollections and forgotten feelings, Kelsey nonetheless expects Laura's memory to vanish forever-only to wake up the next morning to Laura sleeping beside her.
This new Laura has no memory of the cancer, no memory of her son, and, most importantly, no memory of the schism between the two women. Laura's reappearance might just provide Kelsey an opportunity to rewrite history. But as the new Laura begins to question her lack of memories and her increasingly threadbare sense of self, Kelsey will be forced to confront her own incredible involvement not only in the birth of Laura's ghost, but also in the original Laura's death.
