The Cahills aren't the only family searching for the Clues. . . . The Cahills thought they were the most powerful family the world had ever known. They thought they were the only ones who knew about Gideon Cahill and his Clues. The Cahills were wrong. Powerful enemies-the Vespers-have been waiting in the shadows. Now it's their time to rise and the world will never be the same. In Vespers Rising, a brand-new 39 Clues novel, best-selling authors Rick Riordan, Peter Lerangis, Gordon Korman and Jude Watson take on the hidden history of the Cahills and the Vespers, and the last, terrible legacy Grace Cahill leaves for Amy and Dan. It was always leading to this.
I didn't like this as much as I did previous books in the series. The book is divided into four sections; one about the beginning of the Cahill/Vesper war, a view into who Madeline Cahill was, a mission a thirteen year old Grace undertakes and the continuation of Amy and Dan's story. I thought I'd enjoy delving into the history of the family but honestly, the first two parts kind of dragged.
On the other hand, I enjoyed the last two. The mission Grace undertakes was interesting and I enjoyed the ingenuity she uses to hide the ring. She breaks her arm and needs a cast, so when she finds the ring, she digs out some of the cast, hides the ring and then reapplies the plaster bandages to hide what she did. And the final section is full of the action packed plot I came to expect of the series. Except this time, the enemy isn't family and they have no qualms about killing Cahills who get in their way.
