Donald Trump's presidency has been the subject of a number of tell-all books, mainly written by former White House staffers, but the latest one comes from a member of his own family.
His niece, Mary Trump, is a clinical psychologist who has long been estranged from her uncle. Her book, Too Much and Never Enough: How My Family Created the World's Most Dangerous Man, will be released next week.
She describes the president as a narcissist and a bully, and details how the Trump family's history of darkness, dysfunction and brutality turned him into a reckless leader.
US-based columnist Edward Luce, Associate Editor of the Financial Times and author of The Retreat of Western Liberalism, joined us to give his thoughts on the book and what kind of impact it might have.
