I'm still not crazy about short stories, although this one certainly belongs to the better collections I read. There was a little bit of everything, from suspense - in 'Free Radicals" a retired woman faces a killer who tricked her into letting him into the house - to certain eroticism in a naked dinner in"Wenlock Edge," although the whole scene seems quite irrelevant for the rest of the story.
The only one I couldn't really get into was the title story "Too Much Happiness" about a female Russian mathematician/novelist. It was kind of an unfortunate hybrid between a short story and a biography, too long for a short story, and too short to be the real biographical piece. It didn't help that the story was read with a horrible "Russian" accent in the audiobook version. I prefer my audiobooks being read to me, not acted.
