Vespers Rising 39 Clues

This book has 4 stories in it, one from the 1507, one from 1526, one from WWII, and one from present time. In the first one, a man named Gideon concocts a serum that makes a human super strong, super fast, and super smart, but there are serious side effects, including death. A man hungry for power kills Gideon to get the serum, but fails to obtain it. In the second story, the daughter of Gideon, is to protect a gear that could end the world if it falls into the wrong hands. The same Greedy man, Lord Vesper, tries to get the gear also, but fails again. In the third story, the same gear is given to a girl to steal from George S. Patton, who is a villain that stole the gear from the girls family, and the girl succeeds. In the last story, 2 kids are to find the gear and keep it from 2 ruthless villains that will stop at nothing to get it.
I rate this book 5 stars because it had a lot of action in it.
