On the south coast of Japan, everything is in a state of chaos. First, the earthquake hit. Then, the ensuing tsunami—a tragedy that took countless innocent lives. Now, to make matters worse, the damaged Fukushima nuclear power plant is spilling radioactive water out to sea.

Desperate to stop this ecological disaster in the making, Japan’s top scientists have called upon Dr. Tim Collins and Professor James Donaghey for help.

But poisonous water isn’t the only threat facing this battered region. Priceless antiquities, irreplaceable pieces of Japan’s history, have been stolen from area museums—and the hardened gangsters known as the Yakuza are likely responsible.

When FBI agent Buddy Burger is called in to aid local law enforcement in tracking down the thieves, there’s only one guy he can think of to help him get the job done: NYPD detective Mick O’Shaughnessy.

In the thrilling conclusion to the Barracuda trilogy, Micko is reunited with old pals as they work on solving these growing catastrophes—and preventing one surviving barracuda, far from the safety of Bikini Atoll, from carrying out her final act of revenge.
