Lucy Morrigan, a young genetic researcher, lives with her boyfriend, Gray, and an odd collection of tenants in her crumbling family mansion. Surrounded by four generations of clothes, photographs, furniture, and other remnants of past lives, Lucy and Gray's home life is strangely out of touch with the modern world—except for Lucy's high-tech lab in the basement. Frustrated by her unsuccessful attempts to attain motherhood or tenure, Lucy takes drastic measures to achieve both. Using a bloodstained scrap of an apron found in the attic, Lucy successfully clones her grandmother Mary. But rather than conjuring a new baby, Lucy brings to life a twenty-two-year-old Mary, who is confused and disoriented when she finds herself trapped in the strangest sort of déjà vu: alive in a home that is no longer her own, surrounded by reminders of a life she has already lived but doesn't remember. A remarkable debut novel, Mary Modern turns an unflinching eye on the joyous, heartbreaking, and utterly unexpected consequences of human desire.
