I'm also embarrassed about reviewing the book. If I actually knew papersky rather than just reading her journal and occasionally making comments (which usually seem to annoy her) it would be much easier, because I could just ask if she wanted me to review it or not. But talking about someone that I sort of know only not actually feels really odd. And it's worse when the book was a present. I think my problem is that I haven't really got over the idea that being dead is a necessary qualification for being an author.
Anyway, because I am a completist, I decided to publish my review in spite of being all awkward and not knowing what the polite answer is. At least I have mainly good things to say, because otherwise I'd feel really embarrassed.
