Spaceling
by Doris Piserchia
Pretty much as bizarre as I remember. I think another reviewer called Piserchia's work dreamlike, and I'm going to second that description. The kind of dream where everything is extraordinarily complex but it all makes perfect sense at the time and it's only when you try to describe it later that you realize you don't quite know where to start.
I really like the dizzying narrative leaps in time and place. Unlike many first-person narrators, Daryl tells her story like she's standing there in front of you---she skips the parts she considers uninteresting or irrelevant, and you have to infer her (sometimes warped, sometimes unreliable) thought process. Not everything is spelled out! You can return to Spaceling over and over and understand a little more each time.
(5 July 2013) I don't know where I got Spaceling other than that it was during high school, but I recently rediscovered it and remember it as a very weird but very awesome and intricate book.
