I’ve just come across Barry Eisler‘s books. Barry is a former CIA employee who writes thrillers about a half-Japanese, half-American freelance assassin named John Rain. Very compelling with plenty of gadgets – many of them lethal! There are six books so far in the series, starting with Rain Fall. The UK edition of Rain Fall has some nice touches at the back including some personal safety tips from John Rain and an excerpt from The Rough Guide to Tokyo. Highly recommended – I’ve just ordered the second book, Blood from Blood!
