The series continues to please (first book reviewed here), delivering adventure, mystery, and cryptic messages. It is packed with non-stop excitement as the Cahill family goes from danger to danger. I was a little disappointed they stooped to stealing, but I still had to finish the book to know what happens. It was a quick read and grade school to middle school kids will love figuring out the clues and playing online.
Some mild fighting.
