An exciting middle grade treasure hunt mystery adventure set in the Netherlands.

Twelve-year-old Tessa was looking forward to baking cookies, relaxing, and spending time with her best friend Dennis in their Clubhouse, but with the sudden arrival of Katie - her perfect gymnast cousin from the US – Tessa's plans change. Katie isn't very nice at the best of times, but now has turned downright hostile, and is threatening to ruin everyone's summer.

When they find a buried chest next to the local dolmen (their small Dutch town's only interesting feature) it sends them on a hunt for a stolen treasure across the Netherlands. Dennis is thrilled they're going on a real-life treasure hunt, even if he is a little disappointed that there are no pirates involved. But Tessa has wanted to be an archaeologist for as long as she can , and knows these items of historical value belong back in a museum.

Soon they discover that they are not the only ones who are after the treasure. They have to form a team and work together, because if the treasure falls into the wrong hands, it will disappear forever.

For readers with a taste for mystery and solving puzzles, who enjoy learning some fun facts along the way.
