A balanced review from WSJ; the second paragraph says:
His memoir, “Nine Lives,” should dispel doubts about the essential truth of his tale. Detailed and weird, it contains enough verifiable fact, and enough idiosyncrasy, to establish, as his co-authors Tim Lister and Paul Cruickshank write, that “there simply wasn’t another informant inside al-Qaeda like him.” Mr. Dean’s book is a major contribution to the literature of espionage, and a rare book to say something original about contemporary jihadism.
