This such a fantastic series. Very exciting to find out what happens for the 39 clues also what happens to Dan and Amy too. I loved the fact that all the book were written by different people, it gave the series a bit of an edge and each book was a very good follow on from the last one.

The book is nice, the cliffhanger of the prior book is kind of solved and it is almost an happy end with new danger approaching. I am just not sure if I am really satisfied with the turn of the events. Isabel as prime evil and now busted for murderer of the parents of Amy and Dan? Too obviously that this wasn't the last time we heard from her. I was a bit disappointed, when I discovered that there aren't 39 books, one for each clue, but instead every branch already collected like ten clues.
