Action takes place in the Black Sea and the Mediterranean Sea, much of it under the water. There are shipwrecks, mysterious deaths, explosions, kidnappings, drones, revenge and more. All put together to produce a rip roaring tale of derring-do.
There are some really nasty characters, not the sort you would want to meet on a dark night. Their reasoning for much of what they do seems to me to be based on madness brought on by grief, or because of a sense of duty. Watch out for the appearance of Clive Cussler himself as a character – he gets into all the books somehow!
If you want a bit of excitement then this is the book for you.
