Poseidon's Arrow

Penguin presents the unabridged, downloadable, audiobook edition of Poseidon's Arrow by Clive Cussler and Dirk Cussler, read by Scott Brick.

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.
