"Meet the Keller family, five generations of firstborn women-an unbroken line of daughters-living together in the same house on a secluded olive grove in the Sacramento Valley of Northern California. Anna, the family matriarch, is 112 and determined to become the oldest person in the world. An indomitable force, strong in mind and firm in body, she rules Hill House, the family home she shares with her daughter Bets, granddaughter Callie, great-granddaughter Deb, and great-great-granddaughter Erin. Though they lead ordinary lives, there is an element of the extraordinary to these women: the eldest two are defying longevity norms. Their unusual lifespans have caught the attention of a geneticist who believes they hold the key to breakthroughs that will revolutionize the aging process for everyone. But Anna is not interested in unlocking secrets the Keller blood holds. She believes there are some truths that must stay hidden, including certain knowledge about her origins that she has carried for more than a century. Like Anna, each of the Keller women conceals her true self from the others. While they are bound by blood and the house they share, living together has not always been easy."--Dust jacket.
