El misterio del ojo esmeralda

When Tea Stilton turns up an old map at a flea market, hinting at treasure buried on a distant island, she and Geronimo can't resist — and soon they're setting sail with Trap and Benjamin to find it. The voyage goes wrong fast: a violent storm sinks their ship, and the crew survives only by clinging to a floating trunk, using a bathrobe as a makeshift sail to reach land.

Stranded and improvising — sleeping in trees, dodging danger, laughing through disaster — the friends finally track down the legendary "Emerald Eye." The twist: it isn't gold or jewels at all, but the lush green island itself. A fast, funny adventure from the long-running Geronimo Stilton series.
