Tad Williams was just on PRI's "To the Best of Our Knowledge". Yay, Tad. If you haven't read any of his work, you're missing out. Definitely one of the finest fantasy authors around today. War of the Flowers -- a standalone, reasonably short novel, which is unusual for him -- was excellent. And disturbingly prescient, given that he started on it before various recent global political happenings.
I should acquire the S'march book. It has allegedly had a fair bit of material added since its online-serial incarnation. Should be interesting.
