Chick Nonfiction?

Douglas Brinkley reviews The Obamas by Jodi Kantor:

“The difference when a head of state’s spouse performs an advisory role is that both the content and its consequences resonate through a lot more than one household. And that’s the point of Jodi Kantor’s new book, The Obamas. Call it chick nonfiction, if you will; this book is not about politics,
it’s about marriage, or at least one marriage, and a notably successful
one at that.”
