NEW YORK (NYTIMES) - 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 US$65 million (S$85 million), have been subject to widespread speculation.
"Writing Becoming has been a deeply personal experience," Michelle Obama wrote on Twitter on Sunday (Feb 25).
Crown wrote in a statement that the book will also touch on Michelle Obama's time in the White House, motherhood and her public health campaign and more.
The book will be published simultaneously in 24 languages; an audio edition, read by Michelle Obama herself, will be released at the same time.
She also announced that a million copies will be donated to First Book, a nonprofit that provides books and learning materials to children.
Michelle Obama's previous book, American Grown, promoted healthy eating through recipes and historical vignettes.
Barack Obama has yet to release the details of his own memoir.
