Launched from the Castle is the seventh book in a highly addicting series in which three teenagers have the opportunity to travel the world (they're in Frankfurt, by an old castle...). 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 personally found this installment incredibly creative; the bad guys have some really ingenious tactics and plans!!!
