I just finished The Swarm by Frank Schatzing. I was given this book by a friend of mine when he visited last year but I'm just getting around to it now. It's a translation of a German bestseller and fits in the techno-thriller category.

The basic plot is that a series of odd incidents start to point to a strange fact - that the ocean's creatures seem to be working together to kill of humanity! If you've read any Michael Crichton, this book will be very familiar - descriptive catastrophes, lots of scientific background noise, some mostly wooden characters, evil government agents and humanity over-stepping it's bounds and getting into trouble.

The plot is mostly fun and the early catastrophes are interesting but the book bogs down a little once people figure out what is going on and the inevitable mixed expedition of scientists and military set out to fix it.
