Reddit reviews The Eleventh Hour: A Curious Mystery

The Eleventh Hour?

Also (kind of) similar in a more entertaining and light-hearted way is Graeme Base's Eleventh Hour. It's a children's mystery book filled with marvelous illustrations that hold hundreds of hidden codes and messages that, when deciphered, help the reader solve the mystery of who ate all the food at Horace the Elephant's party. Worth checking out.

Missing the Eleventh Hour. Kind of a disappointment. Got a shout out in the comments, though.

highlights puzzlemania!! i used to love them when i was 8-11yrs old.
i'd also recommend The Eleventh Hour by Graeme Base. Very challenging puzzle/mystery book with a ton of codes, hidden messages, and puzzles to solve. And the illustrations are awesome.

Perhaps The Eleventh Hour or one of the other Animalia books?

Sounds like The Eleventh Hour by Graeme Base. He also wrote Animalia.

A Walk in the Woods is about my home hiking trail: the Appalachian Trail. This trail was basically in our backyard and I would hike there often before I went off to school in Idaho. We're now settled in Texas so to go hiking we'll need to trek a bit further.

A great book I read recently was Hawaii and it was marvelous. Its no wonder Michener was awarded the Pulitzer for his work.

For kids, I would recommend The Eleventh Hour. Its a mystery about a birthday party and a delicious meal. Very fun. Young kids will really like the pictures and the older kids will like trying to solve the mystery.
