Query: It's rare that I don't finnish a novel

I usually slog through to the end, even if I'm not really enjoying it.But I just couldn't bring myself to start another 10 page chapter on the protagonist's dating woes. I picked this book up because I thought the idea of a new universe appearing inside of a particle accelerator was interesting. So far, 100 pages in, the science fiction has been a subplot to the more important story about how tough it is to juggle an academic carreer and still have a social life.Benford ought to realize that people read science fiction for the ideas, the science, not deep character studies. No one expects Les Miserables when they pick up a book of hard science fiction.
