IF you’ve been following the buzz on this book, you may wonder how Jodi Picoult and Jennifer Finney Boylan—two very different kinds of authors—decided to team up on a novel. As the story goes, Boylan dreamed that she’d written a book with Picoult, and she tweeted about it. Picoult saw the tweet and said some version of “Why not?” This is an important fact to know when you pick up Mad Honey. There’s a larger reason for the presence and contribution of both authors, and it lies within the story.
