If you're planning on going on a vacation with your mom or your sister, Where'd You Go, Bernadette is an excellent literary companion. Maria Semple's touching, can't-put-it-down novel follows 15-year-old Bee and her agoraphobic mother, Bernadette, who vanishes seemingly without a trace. Bee goes on a mission to track down her mom, compiling email messages, official documents, and secret letters, to piece together wherever it is that Bernadette went.
