"Brilliant in parts but poorly argued and odd" pretty much sums up a LOT of Sheri S. Tepper's work, I imagine. I enjoy some of her books, but it tends to be as a kind of... liberal wish fulfillment guilty pleasure? Some jerkbutt pro-lifer gets loud, and I scoop up a copy of Fresco and go "EXCUSE ME I HAVE TO GO RE-READ THE BIT WHERE THESE DOUCHENOZZLES ARE ALL IMPREGNATED BY ALIEN WASPS."
