Day of Doom by Tyler

This was the final book in the Cahills vs Vespers series, that followed up the 39 Clues Series that I read earlier this year. I'd been waiting to finish the books, and I just earned a special reading award that came with a gift card to Barnes and Noble. I decided to spend my money on this book! And, I'm glad I did!

In this book, Dan and Amy, with the help of their family, stopped the Vespers from starting up the Doomsday Device. This device was going to destroy the planet, but luckily, the Cahills got to it first. In this book, even Isabelle Kobra turned into a good guy, when she realized that the Vespers had killed her daughter, named Natalie. All along, Isabelle had been the ultimate villain, even shooting Natalie in the foot, at one point. I was shocked that she came to the good side. Sinead turned back from being a mole for the Vespers and ended up helping Amy and the rest of the Cahills. I was happy with how the series ended, and I'm glad that the Cahills were safe. I was worried, though, when Amy was struck by a chunk of rock in the head. She started having visions of her dead family members, and I thought she was a goner, too!

Next, I'm going to read the Infinity Ring series, which is by the same authors as the 39 Clues Books and the Cahills vs Vespers. The Infinity Ring are not books about the Cahills and Vespers, so I'm ready to meet some new characters!

Cahills vs. Vespers Series (1-3)

Title(s): The Medusa Plot, A King's Ransom, The Dead of Night
Author: Gordan Korman, Jude Watson, Peter Lerangis

What is the series about?
The series is about the Cahills and Vespers fighting. The Vespers are capturing  the Cahills and threatening to kill them. Dan and Amy Cahill have to keep their family alive by doing what the Vespers tell them. They won't kill them if Dan and Amy Cahill do what they say.  They have had to steal things from museums, and they are always under a strict time limit of 4 days.
 
How is it similar to the 39 Clues series?
It's similar because there are some of the same characters, like Dan and Amy Cahill. Some other chracters come back, too, like Nellie (the Au Pair), Fiske (their uncle), Uncle Alistair Oh (another uncle), and Hamilton, Ian, Natalie, and Jonah. Also some of the places are the same, like Paris. They are always having to hunt for things all over the world.

How is it different than the 39 Clues series?
The difference is that there weren't any Vespers in the 39 clues series. The Cahills are all united and working together in this series of books, working against the Vespers. There are some new characters, also. Dan and Amy work with Sinead (who is like a sister to Amy), Jake and Atticus (they are brothers who decide to help Amy and Dan), and all of the Vespers (they are numbered, as in Vesper 1 through Vesper 6).

Which of these was your favorite book? Why?
The Dead of Night was my favorite book because of the traveling in the story. They traveled to Turkey, while Hamilton, Jonah and the messenger went to Pompeii. They were in search of an Astrolabe. I also liked the mystery in the series.  One twist was that Ian went to visit his mother in New York, and no one knows why. She ended the 39 Clues series as a villain and murderer. She even shot her own daughter.
