It's difficult to write a book about memory loss that's different from all the other books about the topic. And so Liane Moriarty's "What Alice Forgot" starts off on a not-too-different trajectory to Sophie Kinsella's "Remember Me", with a heroine who doesn't remember the last x years of her life, and finds herself older, fitter, and richer.
Nevertheless, the plot diverges from there, and the resulting story is riveting. Beautiful writing. Realistic characters. Spot-on observations about love and marriage.
