It’s December 1997, and a man-eating tiger is on the prowl outside a remote village in Russia’s Far East. The tiger isn’t just killing people, it’s annihilating them, and a team of men and their dogs must hunt it on foot through the forest in the brutal cold. As the trackers sift through the gruesome remains of the victims, they discover that these attacks aren’t random: The tiger is apparently engaged in a vendetta. Injured, starving, and extremely dangerous, the tiger must be found before it strikes again.

Finding and identifying a pirate ship is the hardest thing to do under the sea. But two men—John Chatterton and John Mattera—are willing to risk everything to find the Golden Fleece, the ship of the infamous pirate Joseph Bannister. At large during the Golden Age of Piracy in the seventeenth century, Bannister should have been immortalized in the lore of the sea—his exploits more notorious than Blackbeard’s, more daring than Kidd’s. But his story, and his ship, have been lost to time.

On a foggy July evening in 1956, the Italian cruise liner Andrea Doria, bound for New York, was struck broadside by another vessel.

But the Andrea Doria is still taking lives. Considered the Mt. Everest of diving, the Andrea Doria is the ultimate deepwater wreck challenge.
