It's probably old news to other people (especially since there seem to be a few novels by her already) but I was just adding the latest new books to the Encyclopedia's list of sources and it turns out Sandy Mitchell, author of the Tilean Rat story from a long while ago, has her own novels out.
Even strange is that they're new novels as well. She must be one of the few GW novelists to still be going (especially since Bill King no longer writes Gotrek)
