"Writing Becoming has been a deeply personal experience," Obama, who previously wrote 2012's American Grown: The Story of the White House Kitchen Garden and Gardens Across America, said in a social media post. "It has allowed me, for the very first time, the space to honestly reflect on the unexpected trajectory of my life. In this book, I talk about my roots and how a little girl from the South Side of Chicago found her voice and developed the strength to use it to empower others. I hope my journey inspires readers to find the courage to become whoever they aspire to be. I can't wait to share my story."
