"More than 887,000 units in all formats and editions in the U.S. and Canada on the first day of [the book's] publication" were sold, including pre-orders, the publisher was quoted as saying and adding that this was its "largest first-day sales total for any book ever published."
According to the report, the first-day sales of "A Promised Land" by the 44th US president are poised to overdo the "Becoming," a book by former first lady Michelle Obama, which sold 725,000 copies on its own first day back in 2017.
The first volume of "A Promised Land" is a memoir that describes both Obama's rise to power and also events during his presidency from 2009-2017. His earlier books also proved popular with readers, with "The Audacity of Hope" bringing him $8.8 million and "Dreams from My Father" bringing $6.8 million.
