Raise the Titanic! by Clive Cussler
Book starts out in 1900's and it's the night of the sinking Titanic where a man aboard knows the ship hit the iceberg and will sink as he goes to where he's stored the element that was mined that will be needed for future war projects.
Story follows a lot of different groups: one who finds the horn-the horn that was played on the Titantic, Sicilian project, money paid to survivors from miners who died in the past, other private groups that are funded from the government, the President who pursuades others to do things they don't really want to do and a lot more in different countries.
There is so much action and adventure, never mind the mystery surrounding it all. Bit of romance and you have a well rounded book for everybody.
Byzantium is the special mineral that everybody wants a piece of. two month submersible that can stay under water for more than 2 months time might just be the answer they need to get the minerals.
Thing that amazes me is that this book was written before they even located the Titanic so this is quite the story about it all.
Just when things are on an even keel a hurricane is in the area...
I received this book from National Library Service for my BARD (Braille Audio Reading Device).
