In this book, Greg has become one of the legendary Musketeers. Even after saving Paris, he and his friends are in prison. This is because they have fallen into a trap set by Milady and Prince of Condé. Greg, Aramis, Athos, and Porthos have to King Louis. He is in immediate danger of being overthrown by Prince of Condé. To save the king and history, the boys must escape from prison. Then, defend Louis and hopefully go back to the 21st century before it's too late. I would give this book a 5 star review as it is a great read for everyone.
