The Rising Sea by Clive Cussler

...MORE
Everywhere, waters are rising–and that is just the beginning of the world’s peril, unless the NUMA crew can beat the clock in this thrilling novel from the #1 New York Times-bestselling grand master of adventure. An alarming rise in the world’s sea levels–much larger than could be accounted for by glacier melt–sends Kurt Austin, Joe Zavala, and the rest of the NUMA scientific team rocketing around the globe in search of answers. What they find at the bottom of the East China Sea, however, is even worse than they imagined: a diabolical plan to upset the Pacific balance of power–and in the process displace as many as a billion people. This is 2018 paperback in good condition. It's been a read a few times but is still a great buy for the price.
