Junior is the Timmi Tobbson «early reader» series for adventurers and sleuths aged 6-8. In this series’ first title, a secret message in an ancient book sends Timmi and his friends – including a three-legged frog – on a wild ride to unravel a life-changing mystery and become the Young Explorers.

In typical Timmi Tobbson fashion, each Junior book offers solve-them-yourself picture mysteries, but that’s not all. Accompanying the story is additional content aimed at sparking interest in technology, history and science in general.
