In one of his most daring exploits, Jack goes down under -- literally -- to investigate the disappearance of a diver off the Great Barrier Reef of Australia. Using everything in his backpack arsenal from anti-puke pills to a morphing suit, an egg-shaped submarine to Disappearing Milk, he exposes a deadly nest of pirates raiding a shipwreck site. Jack has to thwart their schemes, evade their attempts on his life, and escape the primordial hunger of three deadly species: a Komodo dragon, a set of sharks, and the most poisonous predators in the reef, the Irukandji jellyfish. Can he save the treasure and the diver, not to mention himself? Canny and resourceful, Jack will delight readers and impress their parents.

In The Mystery of the Mona Lisa, Jack is sent to the Louvre Museum in Paris to track down the theft of the world's most beloved painting. He must match wits with a seemingly invisible mastermind in order to stop Leonardo's masterpiece from slipping into the criminal underground forever. Can Jack's Hypo-Disk overpower a glove that shoots laser beams from its fingertips?

The Mission to Find Max (Book 14) Jack joined the Global Protection Force for two reasons: to thwart evil around the world and to rescue his brother, Max, who went missing while working as a GPF agent. The GPF refused to share any details with Jack about Max's whereabouts, but on two previous missions, Jack had collected clues that pointed to Max is being in Egypt. Now Jack has reason to believe that King Tut's diadem -- a crown thought to have magical powers -- is the cause of Max's disappearance. The crown was so important that King Tut was buried with it on his head, but when the boy-pharaoh's tomb was opened in 1922, an assistant archaeologist named Omar Massri stole the artifact. Could a descendant of Massri somehow be involved in Max's disappearance? Jack and his old friend Kate must prevent an ancient and terrible curse of the pharaohs from wreaking havoc, or else Egypt -- and Jack's brother -- could be doomed.

Deep inside China's famous Wolong Nature Reserve, an endangered Giant Panda named Ling has disappeared, and for his seventh mission, Jack is paired with a surly, sixteen-year-old park assistant named Fong to help track the panda down. As a member of the evil Scorpion Gang, Fong and a partner Wong have been posing as assistants to steal Ling, and several other rare creatures from the reserve to sell on the black market. Now Jack must infiltrate the ruthless gang's Beijing headquarters, overrun with menacing teenage thieves, and rescue Ling and the other animals before they, and maybe Jack, disappear forever.

The Hunt for the Yeti Skull (Book 13) Jack has become the most decorated secret agent for the Global Protection Force, but during the day he's still just an ordinary kid who has to put up with annoying people—like Marko Mayer, a new student in Jack's rock-climbing class. When Jack and Marko race to the top of the wall, Marko stomps on Jack's hand and wins—then has the nerve to gloat! But Jack has no time to sulk—the GPF needs him in Nepal. A plane carrying a team of scientists has gone missing over Mount Everest. They were thought to be carrying the first true Yeti skull ever recovered—proof that the legendary Abominable Snowman really existed. Jack quickly discovers that a greedy collector is behind the theft—and he may have hired Jack's archnemesis for the job. Can Jack and his fellow agents use their climbing skills to brave the highest mountain on earth and recover the priceless skull?

Jack finally receives a coded message from his brother Max, possibly detailing his whereabouts. But duty calls, and Jack is whisked away to the sweltering savannah of Kenya before he can decipher it.

Jack must find the malevolent ring of poachers responsible before more of these endangered species are destroyed.
