Parasite Pig was released more than 20 years ago (and almost 20 years after Interstellar Pig was released) when I was in my early 20s. I remember seeing it on a spinny rack at my local library and thinking "huh, interesting choice for a sequel" but not checking it out bc I was in my early 20s and oh so pretentious about my reading (at the time, I was mostly reading Douglas Coupland, DFW, and [always] Tom Robbins). Once I got over myself, and started not giving a fuck about re-reading childhood favourites, I started actively looking for a copy of this book, but couldn't bring myself to shell out the money for a used, not great condition copy (plus shipping!) of a mass market paperback that I might not even like.  I almost bought it so many times, but never pulled the trigger for one reason or another. Then I'd forget about it for a few years, almost buy a copy, rinse, repeat.

Found it at my library this week, and finally read it. I didn't love it as much as I did Interstellar Pig (which, honestly, still holds up), but I did still enjoy it quite a bit. I like that it was left open-ended, in case Sleator had decided to return to it before his death, and definitely would have read a potential third volume. 

Also, howtf did I manage to read two books in as many months with toxoplasmosis as a motivating factor. Fuckin weird.
