Volume one of former US president Barack Obama's anticipated memoir A Promised Land is to be published, chronicling his thoughts on the global financial crisis, Deepwater Horizon and killing of Osama bin Laden.
The book charts Obama's political education and journey to becoming 44th US president, along with "the landmark moments of the first term of his historic presidency", says publisher Penguin Random House.
"I've tried to provide an honest accounting of my presidential campaign and my time in office: the key events and people who shaped it; my take on what I got right and the mistakes I made; and the political, economic, and cultural forces that my team and I had to confront then - and that as a nation we are grappling with still," Obama said in a statement.
"I've also tried to give readers a sense of the personal journey that Michelle and I went through during those years," added US President Donald Trump's predecessor who served from 2009 to 2017.
The 768-page book is to be released simultaneously in 25 languages and will also be available as an audiobook read by the former leader.
A release date for the second and concluding volume has not been set.
Obama has previously written two books: Dreams From My Father (1995) and The Audacity of Hope (2006).
