First Person Strange
To explain: this perspective is what you are dealing with when you open up a book that is, either possibly or definitely, set in an alternate Time, Universe, Space or Reality, and where the narrative is told entirely through the eyes (figuratively speaking) and mind of a protagonist who does not ever take the time to acknowledge that you, the Reader, are a Human Being from circa 21st-century Earth. You might get the feeling that the story was written as a journal entry or letter to Another of the protagonist's Kind...in which case, the protagonist isn't going to take the time to tell you what certain words mean, or what he/she/it looks like. Or, worse, they might describe themselves--but those descriptions might be in general terms (e.g. "average height, big feet") so that, at some point later when he/she/it mentions that they breathed fire from their armpit onto a neighboring goat, you are spun back out of Knowing What This Is About into having to flip back through pages to make sure you didn't miss the part where you were told that this was a book about Armpit Dragons. Or at some point in the book when someone drops something and comments that it, "fell up into the sky..." you realize that this book is happening in a place with inverse gravity, and hence all Laws are thenceforth Suspect.
I usually love, or at the very least have much appreciation for, these kinds of books. It's probably why I keep reading Sci-Fi: it's a happy medium between too-arduous/smart-for-me Philosophy and too-simple/straightforward/non-memorable Standard Bestsellers.
Two recent reads wherein First (and Only) Person perspective was employed: The Einstein Intersection by Samuel R. Delany, and Red Shift by Alan Garner. Each book is only about 150 pages long. Each book took me several days/hours to read. And in each book's case, it wasn't until the end that I was fairly certain I knew where, when, and what had taken place (Note: I try not to read the back covers or summaries of books that are new to me until I have read them...reading those back covers can negate the intended First Person Strange effect of any book).
The Einstein Intersection won the Nebula Award in 1967. Red Shift just looked interesting on the shelf at Kramerbooks. I won't give anything away about either book, except to say that Einstein Intersection includes references to physics and mythology (e.g. Orpheus, Theseus, and The Beatles), while Red Shift includes references to (and interactions with) players in both the Roman Ninth Spanish Legion and the English Civil War.
