The mystery deepens and the action intensifies for 12-year-old Cruz Coronado and friends in the exciting third book in the Explorer Academy series.The adventure continues for Cruz, Emmett, Sailor, and Bryndis as they continue their studies at sea and travel to exotic locations around the world. A mysterious person alerts Cruz to impending danger while he and a few trusted pals explore ancient ruins in Petra, Jordan, and search for another piece of the puzzle his mother left behind. Worst of all, now his father has gone missing, which prompts Aunt Marisol, his number one protector, to leave the ship in search of him. Who is the new professor who takes her place? How does the new technology he introduces help or hurt Cruz’s quest? Why is Nebula determined to stop Cruz before he turns 13? The clock is ticking as his first teen birthday draws near … a milestone that will change his life forever, one way or another.

Explorer Academy Recruitment Day — October 10, 2025
October 10th, 2019 is Explorer Academy Recruitment Day. From New York to Vancouver, Ohio to Texas, and all points in between, real-life National Geographic Explorers will be talking to thousands of kids across North America, sharing their experiences and revealing how the Explorers themselves inspired the coolest school on the planet: The Explorer Academy. Explorer Academy author Trudi Trueit will also be in her hometown of Seattle, talking to local schools (if only we could make more Trudi’s to go around but, alas, she is one-of-a-kind). Thanks to the series’ publication in a dozen countries, Explorer Academy Recruitment Day has turned into a GLOBAL phenomenon, with students all over the world participating in events similar to the ones happening in North America.
