Cass, Max-Ernest, and Yo-Yoji get caught up in a mummy heist at the local museum, which turns out to be linked to their quest for The Secret.
A clever finish to a clever and fun series. The plot is fun and inventive, but the best thing about the series is the narrator, who inserts himself into the story frequently and adds a goofy meta-ness to the whole affair. I highly recommend the series for those who like MG-level mysteries with a touch of the supernatural. ( )

3.5/5
Not that great ending to a great series. ( )

Overall, a flat series. Enjoyable, cute, but at the end, I found that the author pulled it all together and made it fun. ( )

The 5th and final book in the secret series.
