Michelle Obama's new book, "The Light We Carry," to be released this fall

Michelle Obama will have a book out this fall, "The Light We Carry," in which she reflects upon her experiences and shares insights on navigating an increasingly stressful world.

It's the former first lady's first entirely new work since the 2018 release of her acclaimed blockbuster "Becoming," which has sold more than 17 million copies worldwide, surpassing the sales of any memoir by a previous first lady or modern president, including her husband, former President Barack Obama.

"I've learned it's okay to recognize that self-worth comes wrapped in vulnerability, and that what we share as humans on this earth is the impulse to strive for better, always and no matter what," Michelle Obama writes in the book's introduction, included in Thursday's announcement by the Random House Publishing Group and its imprint Crown.
