Okay I've finished the Techno-Mage trilogy.
It is one of the best things I have ever read. It is INCREDIBLE.
All during Crusade Galen was my most disliked character, I was always complaining about how emo he was. During this trilogy I kept feeling an overwhelming need to apologize to him for my ignorant attitude. I going to rewatch Crusade as soon as possible.
This trilogy does not read like a series tie in, it's a fantastic story in itself. There is no Treklit even comparable in quality. Some of it was so disturbing and upsetting I had bad dreams about it, at times it was incredibly depressing and tragic.. like the tragedy that was much of Bab 5.
These books are out of print and I ended up buying them through Abe Books.
Here's the Amazon reviews for the first book:
Try not to read the reviews for the next two as you may hit spoilers, this trilogy is full of revelations.
