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 readers who love mystery, adventure, and out-of-this-world secrets.
