When it was published in 2012, Where'd You Go, Bernadette achieved a kind of success that most authors can only dream about. Now, the book is being made into film (Cate Blanchett will reportedly play Bernadette) - and author Maria Semple is returning with another fizzy fiction, also about a troubled young mother holding on by the skin of her teeth. Join Semple as she signs copies of Today Will Be Different, at Barnes & Noble.
