Yeah, I didn't think too highly of the short stories, either. I'm not even sure why "Pip and the Fairies" and the "The Woman in Schrödinger's Wave Equations" were considered SF or Fantasy. And in "Helen Remembers the Stork Club" why would Helen of Troy be all nostalgic about a club that shut down 50 years ago? She's like 3000 years old and she acts like a character from Sex in the City. "Henry James" was more of an idea story, but the idea wasn't particularly new, and I think the publisher would have seen dollar signs instead of the end of his carreer. I guess they were well written, but I read this stuff to escape. Except for "Echo" (which I thought was kind of obtuse), all of these were set in modern times, and the characters faced modern times problems.
"An End to All Things" has only recently become available online, and I haven't had a chance to hit it, yet.
Of the Novelettes I liked three of them. I'll hold off my comments until you (or anyone else) get a chance to read them. I haven't read any of the Novellas yet.
