Memoirs, of course, are a famously imperfect art form. Inaccuracies and omissions appear in classics by Henry Adams and Benjamin Franklin and countless other works. While few are reduced to proven deceit, such as James Frey's "A Million Little Pieces," even the best books are only as reliable as memory itself.Who among us can accurately remember events that occurred when we were children — much less in the environment of being trained to be a mercenary killer? I can't even imagine what that would be like.
Thus, this title remains one of my most memorable books from 2007.
