Where'd You Go, Bernadette by Maria Semple

Bernadette Fox has vanished.

When her daughter Bee claims a family trip to Antarctica as a reward for perfect grades, Bernadette, a fiercely intelligent shut-in, throws herself into preparations for the trip. But worn down by years of trying to live the Seattle life she never wanted, Ms. Fox is on the brink of a meltdown. And after a school fundraiser goes disastrously awry at her hands, she disappears, leaving her family to pick up the pieces--which is exactly what Bee does, weaving together an elaborate web of emails, invoices, and school memos that reveals a secret past Bernadette has been hiding for decades. Where'd You Go Bernadette is an ingenious and unabashedly entertaining novel about a family coming to terms with who they are and the power of a daughter's love for her mother.
