Timmi Tobbson Young Explorers

Timmi and his friends enjoy Christmas break when they find a mysterious package. Whoever left it needs help ... and a little Christmas miracle.

Timmi, Lilli and Marvin are allowed to visit the excavation site and soon find themselves following the mysterious trail to an ancient and well-guarded secret. Behind the scenes, an unscrupulous adversary is pulling out all the stops to prevent their discovery.

Young Explorers 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 Young Explorers 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.

A wave of jewelry thefts is committed in broad daylight and without any trace. When grandma's old and beloved family necklace vanishes, Timmi, Lilli and Marvin set out to catch the phantom known as the Invisible Thief.
