The only book of his I read was
Neverness, and that a long time ago, but I liked it and I plan to reread it soon, and also read the sequel trilogy now that they're out as ebooks.
This review is for
The Broken God but I think the sentiments also apply to Neverness from what I remember of it.
He is American but I gather he was better received in Britain than at home, which might be why the ebooks have not been released in the US.
