This must be my favorite book ever! When 3 kids are genetically enhanced as babies, when they grow up they are put into the water and must survive bounty hunters and the coast guard hunting them down. While the kids try to meet a rendezvous with other Neptune Kids they have to run through the perilous waters until they meet the other. When they are united, they must survive together. Through giant squids, food problems, sharks, and what ever the ocean can throw at them. They survive the best they can. This book will make you laugh and cry, it is an all time favorite for me!
