The World’s Strangest Mysteries For Curious Kids: Explore the Weirdest Facts, Wildest Events, and Most Surprising True Stories Ever Told (The World's Curiously True Series)

The unsolved mysteries book for curious kids ages 8 to 12 that reads like a wild investigation, not a textbook.

25 real cases. Nobody on Earth has solved them.

Stones older than civilization, dragged across continents with no wheels. A whole colony that vanished with dinner still on the table. A book written in a language nobody can read. A radio signal from deep space that lasted 72 seconds and never came back.

Your kid is about to try to crack them.

Their guide is Agent Blip , an alien investigator from Planet Zog who got stuck in a black hole made of lost socks, calls Earth a giant mystery burrito, and is currently hiding in your kid's backpack with a magnifying glass.

He brought snacks. He brought theories. He needs a partner.
