When her notorious, hilarious, volatile, talented, troubled, and agoraphobic mother goes missing, teenage Bee begins a trip that takes her to the ends of the Earth to find her. Bernadette Fox is notorious. To her Microsoft-guru husband, she is a fearlessly opinionated partner; to fellow private-school mothers in Seattle, she is a disgrace; to design mavens, she is a revolutionary architect, and to 15-year-old Bee, she is a best friend and, simply, Mom. Then Bernadette disappears. It began when Bee aced her report card and claimed her promised reward: a family trip to Antarctica. But Bernadette's intensifying allergy to Seattle, and people in general, has made her so agoraphobic that a virtual assistant in India now runs her most basic errands. A trip to the end of the Earth is problematic. To find her mother, Bee compiles e-mail messages, official documents, secret correspondence, creating a touching novel about a family coming to terms with who they are, and the power of a daughter's love for her imperfect mother.
