This series is like a roller coaster ride from the beginning till the end and the series final maxed it all out: non stop action once again. Everybody (and I mean everybody!) is back for the end game! ...Ok, I really can't review this part as a stand alone as it rounds up the whole series so nicely. The entire series is fun to read, with lots of combat action, great character development and emotionally very intense at many points.Some might say, the time travel part is not scientific enough and the story is too complex to follow... Come on, not every scifi novel has to be built upon hard science for the story to work! Give it a break :D ...as for the complexity... (Critics say that about Westworld as well and it still is the best damn scifi show I've seen in years...:D) So what, if you have to think it through twice, doesn't hurt to use your brain :DFans of the series will enjoy this part too and as for the sceptics... See section 3 above... again!All in all highly recommended as all other books by Mr. Forbes!
