My favorite is .... well its two books actually. Weavespinner and Subjugation.
Weavespinner is a wonderfully long book that takes Tarrin through the whole of the western world. In that time he grows, matures and fulfills his destiny as a true Weavespinner. He also frees his nemesis and instigates his avenging his lost honor. Oh yeah. He also coordinates the defense of Suld. And, he kicks some butt in the battle of Suld.

Subjugation is, wow. Fel just makes this seem so real to me. The anger that Jason shows. His inner turmoil. His ingenuity. And his history. Oh, yeah then there is the Marine who is after him. Anybody would be afraid of a marine who is out to get you. Too bad she is also a occupier from an alien empire.

Edit by Greymist: You had created two threads with slightly different titles, I presume this was an accident so I deleted the other one. Oh and yes I love Sub, I'd have to read the Sennadar books again though to decide, it has been well over 6 years since I read the first book
