Writing in the London Review of Books, Michael Dobson called the book 'wonderful... a brilliant debut... both enthralling and scholarly." In the Los Angeles Times, Phillip Lopate called it 'Brilliantly engrossing... exemplary... engaging, worldly, fluent... crammed with entertaining nuggets.'.

The book was a New York Times Notable Book and was shortlisted for the PEN Hessell-Tiltman Prize. In the New York TimesEric Ormsby wrote: "Cliff has a novelist's gift for depicting character." In The Sunday Times James McConnachie called the book 'stirringly epic... thrilling narrative." Cliff's third book was a new translation and critical edition of Marco Polo's Travels for Penguin Classics, which was released in the UK and U.S. in 2015. For this first all-new translation in a half-century, he went back to the original texts in French, Latin and Italian.
