In the US, the foreword was written by David Ignatius of The Washington Post. The book received praise in Britain for Begg's "outstanding liberality of mind and evenhandedness toward his captors". It received mixed reviews in the US, Publishers Weekly described it as "a fast-paced, harrowing narrative". "Much of the Moazzam Begg story is consistent with other accounts of detention conditions in both Afghanistan and Guantanamo", said John Sifton, a New York-based official from Human Rights Watch, who interviewed former Guantanamo prisoners in Pakistan and Afghanistan. The New York Times reported "some notable gaps in Mr. Begg's memoir", such as not mentioning his arrest in 1994 for alleged fraud. U-T San Diego said: "Begg has been less than forthcoming about his criminal past ... his cooperation with interrogators ... and his ties to terrorism". Jonathan Raban, reviewing the book for The New York Review of Books, wrote " The gaps in his story — and they're more frustrating than downright suspicious — cease at the moment when Begg enters captivity". Raban criticised some "notably talentless" dialogue writing, "Perhaps Begg really did strike up a warm relationship with soldier Jennifer … but only in bad fiction do people speak this way".
