(From the publisher):
Deep beneath the Caribbean lay a treasure rumored to be worth more than $200 million. Once the plunder of Spanish pirates, the sunken loot interested more than one modern-day buccaneer. But when an archeology professor vanished while searching for the treasure, it was up to Mark Hardin to find him. And the Penetrator vowed he would search for the missing man until the seas ran red with his kidnapper's blood.
