This was probably the best out of the 3.
There was plenty of action and nearly everything was brought to a climactic end.
I even cried a few times. By this time in the books, you really empathize with these characters - even more so if you are an overall Warcraft (WoW, etc) fan.
It took a while for me to finish this series - the first was not very good, but I am happy that I have this one under my belt. The time traveling aspect of these books made things very interesting and it was a smart way to tell this story. It kept me thinking about how things changed the time line of "our reality". It was definitely worth finishing.

Lok'tar and Love to Thrall and Broxigar.
