Escape from the Black Forest is the eigth of a highly addicting series in which three teenagers have the opportunity to travel the world (in Freiburg, Germany/the Iranian border this time). The only catch? They're always chased by Hoffman, a villain who'll stop at nothing to capture the three teens to stop them from foiling his plans to be rich! The adventures will keep you on the edge of your seat. They keep coming, but they're fresh and new in every book!
I've never read a book quite like it; Doyle manages to incorporate incredibly amounts of integrity, adventure, and culture in a short and thrilling read. The setting is unusual, but perfect and fitting for the story.
