Michelle Obama’s memoir, “Becoming,” will hit bookstores on Nov. 13.

It will be published by Crown, a Penguin Random House imprint, which acquired world publication rights of it along with a book by former President Barack Obama in February. (The undisclosed details of the deal, which The Financial Times reported at $65 million, have been subject to widespread speculation.)

“Writing ‘Becoming’ has been a deeply personal experience,” Mrs. Obama wrote on Twitter on Sunday.
