Book 4 of the Cahills vs. Vespers

Amy and Dan Cahill, with their friends, Atticus and Jake Rosenbloom, are on the run from Interpol. They have no choice but to fulfill every demand of Vesper One or else one of the hostages will die.  They are ordered to steal the world’s largest diamond from one of Berlin’s famous museums.  If they do not succeed, what will become of them or the hostages?

The story contains many subplots that keep the reader in suspense.  One episode takes Hamilton, Jonah, and Erasmus on the search for Luna Amato.  Another suspenseful plot involves tracking down the mole at the Cahill compound.  Also the hostages attempt to escape and what happens to them is another plot. Amy and Dan are sent all over the world to fulfill every demand of Vesper One.  They are sent to Timbuktu, Africa to go through thousands of manuscripts looking for “The Apology for a Great Transgression", which was an emblem engraved on a salt tablet.  All of these plot episodes are either revealed during the course of the story or left as a cliff-hanger at the end of the book.  Who is the mole –Ian, Evan or Sinead?  Who dies?  Who escapes and is presumed dead?  These and many more questions are answered or are left for the reader to find out in the next book of the series.  The cliff hanger will keep you on edge for the next book in the series, Trust No One.

This is definitely the best so far of the Cahills vs. the Vespers.  The story is fast-paced, suspenseful, exciting, adventurous and intriguing.  I would recommend this book and the series for children ages 9 – 12.
