Die Jagd nach den magischen Münzen

When Bo finds a shiny coin in the mud of the Thames, she believes she hears the river speaking. "You will not lose..." it whispers to her. But what do the words mean? Billy, the boy from the opposite shore, has no answer either. However, he knows of a second coin, and together they set out to find it before the old Muncaster gets to it first. For he also has his sights set on the magical coins. Will Bo and Billy be faster and recover the most valuable thing they have ever lost?.
