Vespers Rising

From Goodreads:
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, bestselling 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.

The 39 Clues continues! I'll admit that I've been looking forward to this, and the section written by Rick Riordan was really, very good. Emotional and heartbreaking even. All the other authors did a good job too. This is a bridge book between the last series and the new one that's starting soon. Leave it to scholastic to milk this for all it's worth. I'm pretty sure there will be another 10 books coming out for this new series. I love everything about these books: the mystery, the clues, the historical stuff, the travel, the family dynamics, all of it. I'd like to own this whole series, but for heaven's sake it would eat up my entire budget if I bought them all. Series like this make me very, very grateful for the library. :D I'll be checking out The Medusa Plot soon, hopefully! (Medusa!!! Will it have greek mythology in it?? I'm so excited!)
