Just wanted to share some great news. GRRM, my big retrospective collection from Subterreanean Press, got a terrific review today in the WASHINGTON POST BOOK WORLD. "... the most ambitious volume ever to come from an American specialty press" and "... one of the most important -- and generous -- single-author collections of recent years" are my favorite bits, but there's lots of other good stuff as well.
The entire review can be found online here.
