Explorer Academy

Cruz Coronado leaves his tranquil home in Hawaii to join 23 talented kids from around the globe to train at the Explorer Academy with the world's leading scientists to become the next generation of great explorers. But for Cruz, there's more at stake. No sooner has he arrived at the Academy than he discovers that his family has a mysterious past with the organization that could jeopardize his future. In the midst of codebreaking and cool classes, new friends, and augmented reality expeditions, Cruz must tackle the biggest question of all: Who is out to get him, and why?

In the exciting follow-up to The Nebula Secret in the seven-book Explorer Academy series, Cruz, Sailor, and Emmett, along with their new ally Bryndis, embark on their first globe-trotting mission aboard the ship Orion. Cruz jumps right back into school and starts using the latest technology in submersible underwater dives, but is soon reminded of the dangers of exploration when his equipment fails and he almost drowns. Determined to keep his eyes on the prize, Cruz sneaks away to try to find answers, but unknowingly lures his friends into bigger trouble.

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.

A major discovery forces the Explorer Academy into the limelight in The Star Dunes, but Cruz has much more on his mind than 15 minutes of fame. A new face on board the ship brings Cruz's worlds colliding, just as a major close call tears them apart. En route to Africa, Team Cousteau is now down a major player, and Cruz can't help but be preoccupied by the hole in his life.

On an island nation in the Indian Ocean, the explorers venture through a vast underwater world and take part in a friendly robotics competition. But the tides of good fortune change quickly. Suddenly, Team Cousteau jumps into action to rescue a faculty member from the brink of death. Meanwhile, the team follows the Cruz's mother's clues to a magnificent tomb and center of spirituality precariously perched on the side of a cliff. There, Cruz is confronted by a familiar foe who's determined to stop him from completing his most important mission of all.

Still reeling from the life-changing discovery he found buried in the mysterious archive, Cruz Coronado grapples with an important secret as the gang heads to China in search of the second-to-last piece of the cipher. Under the watchful eye of a new adviser, life on the ship returns to almost normal...almost.

The frigid swells off the coast of Antarctica buffer Team Cousteau’s kayaks as they weave through the icy water. They’re losing daylight, and at risk of failing their fieldwork assignment. But Cruz Coronado’s thoughts are elsewhere. Nebula is closing in, and time is running out. The evasive explorer spy is still out there. And in his gut, Cruz knows his final mission will have deadly consequences.
