I love her writing! I am reading now the last book from her "The Liveship Traders" series, and I am already feeling withdrawl pains, knowing that after this, that is it, I wont be able to read anything new about these characters, or anything new from her, period...until she writes a new book.
If you read the assassin series first then comes the Liveship Traders, then it goes back to the original characters one generation on. Tawny Man is the first of the third series she writes in that particular world. I'd recommend it
