My only experience of this author was "Jack Neck and the Worry Bird" in the Mammoth book of Extreme Fantasy and it was probably the weakest story in the entire collection in my opinion. Certainly hasn't made me want to check out any more of his work. Although I shouldn't write him off after one dodgy short story...
[EDIT] Actually, I also read "Providence" in the Solaris book of new SF volume 3 and that was quite good.
