Actually it was kind of a strange road to publication.
Originally an experimental imprint by AOL/TW Book Group called iPublish put it out as an ebook/Print-On-Demand. It had an editor, cover art, all that, so it wasn't self published.
They imploded in Dec 2001 with a lot of other dot-coms...my agent reverted the rights to me again (because they failed to publish the second book) and we were able to sell it to Penguin Group (who put it out in September 2003 through Roc).
WOLF did well, it's in its third printing now and the next in the series, CHOICE OF THE CAT, seems to be selling well.
Anyway, that's my story. Thanks Jeff!
New book out! Cool, will go shopping this weekend.
I wish you the absolute very best as your series continues. I know you have a GREAT future in store.
