One sunny day, Tim and Lily went to the library. The library was big and quiet.

Tim loved books about space. Lily liked fairy tales. They each picked a book.

Suddenly, they heard a soft whisper. 'Find the golden key,' it said.

'Let's find it!' said Tim. They searched the mystery books section first.

Lily found an old book with a shiny cover. Inside, they saw a map.

'The key is hidden,' Tim read from the map, 'under the biggest book.'

They went to the non-fiction section. There was a huge book about dinosaurs.

With effort, they moved the dinosaur book and saw a small door.

They opened the door carefully and found a golden key behind it.

'Let's see what this key opens,' said Lily with excitement.

They noticed a locked chest hidden under the librarian's desk.

The key fit! Inside, they found a book of magical stories and a note.
