"This divinely funny, many-faceted novel...leaves convention behind. Instead, it plays to Ms. Semple's strengths as someone who can practice ventriloquism in many voices, skip over the mundane and utterly refute the notion that mixed-media fiction is bloggy, slack or lazy.... The tightly constructed WHERE'D YOU GO, BERNADETTE is written in many formats-e-mails, letters, F.B.I. documents, correspondence with a psychiatrist and even an emergency-room bill for a run-in between Bernadette and Audrey. Yet these pieces are strung together so wittily that Ms. Semple's storytelling is always front and center, in sharp focus. You could stop and pay attention to how apt each new format is, how rarely she repeats herself and how imaginatively she unveils every bit of information. But you would have to stop laughing first."—Janet Maslin, The New York Times
