A brand-new action-packed series from Michael P. Spradlin. Each book covers a genetically engineered super-predator wreaking havoc on the environment. A long time has passed since anyone heard from Dr. Catalyst. Emmet Doyle and his best friend, Calvin, have even begun to think that the crazed environmentalist might be gone for good. But while taking a day trip to snorkel off the Florida Keys, Emmet and Calvin have a dangerous run-in with a very strange-looking and aggressive barracuda. When a fisherman later captures one of the fish, Dr. Doyle realizes it must be a genetically enhanced species. Dr. Catalyst is back - and hes introduced a new super-predator into the waters.
