The better of the two, but largely the same. I feel like these books are a bit too autobiographical, but I don't know if I'm allowed to accuse an author of that. My real problem is that I read these books as largely uncritical of their characters. They behave in nonsense ways, are mostly uncritical of their own behaviour, and don't really have arcs of growth or change. I suppose this book had a bit of one, but only in the last two chapters.

Unbearably straight. Eyerolls and sighs per page off the charts. Shout out to Joanna, I guess. I kinda like the lack of quotation marks though to be honest. After half of the Ruth Ozeki novel and now this, I need to get back to some genre fiction.

Suffers a little bit from middle book but I really enjoyed it. Read it faster than the first one too, despite its length.

Mixed bag like most collections of short stories. Some of them are pretty good. The author of the worst written story also has the worst written bio.

2022-06-02Use stderr instead of /dev/tty, realloc buffer if lines too longJune McEnroe
For some reason I haven't been able to figure out, trying to poll /dev/tty returns POLLNVAL (and this was using 100% CPU looping), but using stderr instead works fine.
