As the adventures in Willabrook continue, the mysteries are getting bigger... and far more dangerous.
When the stars in the night sky suddenly freeze-and one crashes into the woods-Alex, Jess, and Sam know this is no ordinary mystery. The fallen object isn't a meteor... it's a piece of something much bigger.
Following the clues left behind by the brilliant Mrs. Whitley, the friends uncover a hidden machine that opens a doorway to the Arclight Observatory - a secret space station orbiting high above Earth. But the station is failing, dangerous fragments are falling toward the town, and an ancient cosmic judge known as a Warden has begun to watch.
To save Willabrook, the trio must travel farther than ever before, face a relentless Sentinel, and prove that Earth is worth protecting... before time runs out.
Because this time, the fate of one small town might decide the future of the entire planet.
✨ Perfect for young readers who love mystery, adventure, and out-of-this-world secrets.
