At first, I thought about giving up on the book. The relationship between the characters--particularly their sex life--seemed nothing but unpleasant. Toward the end, however, it became both funny and menacing, which I assume was the author's intent all along. This mood should have emerged earlier, however, to make some of the protagonist's decisions plausible. The degree of their isolation was difficult to believe, as well. Couldn't she just have gotten a job and made friends through it? That's what the rest of the world does, after all.
