Beware! Dangerous secrets lie hidden between the pages of this book. If you think the author is going to give anything away about the ongoing fight against the evil Dr. L and Ms. Mauvais, you are entirely wrong. You certainly will not hear a word about how Cass and Max-Ernest stumble upon the hidden Museum of Magic, or how they finally meet the amazing Pietro. And you definitely will not learn anything about the missing Sound Prism, the nefarious Lord Pharaoh, or the mysterious creature born in a bottle over five hundred years ago who holds the key to the biggest secret of all. But since you are already here, it might be too late to turn back. Join Cass and Max-Ernest as they attempt to unscramble coded messages, solve bizarre new mysteries, and stop the Terces Society's enemies from discovering the secret to immortality. Packed with hilarious warnings, thrilling escapes, and mind-bending puzzles, this second adventure in the Secret Series is impossible to put down.
