Basically, it's about two damaged people drawn together in an adventure fraught with megalodons and kraken monsters, zeppelin airships and nanoagents. Can't say much more without massive spoilers, but seriously, read this. Guys will enjoy the adventure and technology aspects, the romance addicts will be swept away but the grand passion.
All in all, a fabulous time was had while reading this.
