Dirk Pitt, Clive Cussler's greatest hero, returns in the brand new thriller from the Grandmaster of Adventure. All three of Cussler's 2012 hardbacks have been top ten bestsellers and the most recent, The Storm, hit number three in the hardback chart. Cussler is Penguin's biggest brand author with sales totalling almost 5,250,000 in the UK alone. Dirk Pitt is Cussler's best loved hero and fans will be desperate to get their hands on the next instalment in his tale. It's called Rapier. It is the biggest advance in naval technology in decades. An attack submarine capable of incredible underwater speeds. There is only one problem: A key element of the prototype has vanished and the man who developed it is dead. Now Dirk Pitt and his NUMA team must go on a desperate international chase to retrieve it. But as they close in they discover that they're facing a much, much greater threat than they ever imagined. If they fail in their mission, the world might end up a very different place and not a pleasant one.
