The Mills of God

Constance Fairchild is an eccentric heiress haunted by images and dreams she feels are from a previous life. Orphaned at fourteen, she is sent to a Swiss boarding school, where she finds concrete proof of her reincarnation. On inheriting her family's fortune, she stumbles upon a conspiracy to control it that involves murdering her and all her friends. Using knowledge from her previous life, she defeats the conspiracy and resolves her life's central mystery: She is the reincarnation of a computer security consultant her evil grandfather hired and murdered - whose death inspired the conspiracy she'd battled.
