Vespers Rising was a good read, and a great addition to the 39 clues series. I'm so glad that they had the stories of Gideon Cahill, Madeline Cahill, and Grace Cahill in it, otherwise I would've been really confused if they had just started with the part about Amy and Dan. I'm really curious as to what Gideon's ring can do that makes it even more important than the 39 clues and the serum that they create. I can't wait for the next book!!!
