This was so bad!!! Everything about it was failed in my opinion. The characters were not interesting. The story just focus on every aspects that aren't good or interesting and skip really fast what could have been fun. The third of the book is about how the characters are going to get the money for there «expedition» speaking to banker and selling their pitch... who would enjoy reading that. I had the impression of reading about negotiating my mortgage. There is so many loose ends and plot holes and tagging has a time travel novel is truly just a joke. I kept reading expecting something to happen like I didn't believe that it was going to be that all along, but yeah it was.
