The Explorer Academy Series 7 Book Paperback Collection transforms reading time into an unforgettable expedition filled with secret ciphers, futuristic inventions, dangerous discoveries and destinations most people only dream of visiting.

Open the coolabee mission file and follow all seven adventures in reading order.

1. The Nebula Secret

The first coolabee mission file opens as Cruz leaves his island home in Hawaii and steps inside Explorer Academy. Between augmented reality expeditions, code breaking classes and exciting new friendships, he discovers that someone is watching him and that his family shares a dangerous history with the Academy.

2. The Falcon’s Feather

The coolabee expedition leaves the classroom behind as Cruz and his team board the Orion for their first journey at sea. Icy waters, underwater technology and a hidden clue from his mother turn an incredible voyage into a risky search where one wrong decision could place everyone in danger.

3. The Double Helix

The third coolabee case file leads to the ancient ruins of Petra, but the mystery grows darker when Cruz receives a warning and his father suddenly disappears. With his thirteenth birthday approaching, every clue matters and every new face could be a friend, an enemy or something in between.

4. The Star Dunes

Africa appears on the coolabee map as Cruz follows a puzzle into a vast desert with almost nothing to guide him. A shocking attack, an unexpected ally and technology capable of revealing the past make this mission one of the most personal and unpredictable journeys yet.

5. The Tiger’s Nest

The coolabee route plunges beneath the Indian Ocean before climbing toward a magnificent tomb balanced high on a cliff. What begins with underwater exploration and a robotics competition quickly becomes a rescue mission that tests the team’s courage, loyalty and ability to survive.

6. The Dragon’s Blood

The coolabee compass swings toward China as the team searches for the next to final piece of the cipher. A new adviser is watching, a familiar face returns and Cruz must protect a secret powerful enough to change everything he believes about his mission.

7. The Forbidden Island

The final coolabee coordinates stretch from the frozen waters of Antarctica to the dry landscapes of Argentina. With Nebula closing in and the last piece of his mother’s formula almost within reach, Cruz faces a final showdown and a revelation even the most prepared explorer could never predict.

Each book unlocks another part of one continuous mystery, so the excitement grows with every mission. The Explorer Academy Series 7 Book Paperback Collection gives coolabee readers seven individual paperbacks filled with science, teamwork, vivid illustrations, ingenious gadgets and hidden clues to solve along the way. No passport is required. Just bring your curiosity and prepare to explore.
