Greek Gladiator Sharks

Every dive. Every enemy. Every perilous wild adventure.
The Treasure Rebels have survived it all to get to this point. Now one step away from the treasure they have been searching for years to find, the world's greatest treasure hunters must dive the most treacherous shark infested stretch of water in the world to finally complete their crucial mission.
Scuba diving in the Aegean Sea amongst isolated Greek islands, the Rebels must explore the exotic underwater ruins of an ancient gladiator school. But as they embark on their most important dive ever, Maddox, Travis, and Amber are unaware the greatest danger may be waiting for them above the waves.
"Greek Gladiator Sharks" is the fifth adventure in the Treasure Rebels novella series, and directly follows the astonishing events of "India Yeti Pirates."
