This is an exceptional book and a real masterclass in story telling. 

The characters are fantastically written, every single one of them is clearly defined with their own voice and personality.  

The plot is superb, it keeps you on your toes from the first page to the last.  

If you have any interest in good story telling then you need to read this. 

Intriguing enough to make me stay up a few hours late to finish because I wanted to be sure of the ending. Well researched, though of course with it being quasi-autobiographical some of it would be experience instead. Feelings are had, which can be rare in books by/about men. There's a very good line at the end, something like (mild spoiler)
the reality of the kid didn't matter, because it was the reality of the feelings that affected him
that I think was important and tied it together.

I bought this book, for a dollar, based on title and cover alone, and then it sat on my shelf for years with all the other books I impulse-bought for a dollar based on title and/or cover. Then I heard/read the name Armistead Maupin somewhere -- NPR? Newspaper list of famous birthdays? -- and figured I'd finally get around to reading it.

"Ergh," I said, "'A Novel'." That's usually not my kind of book.
"Nooo not an unreliable narrator," I sighed early on as he described himself as such.
"Ughhh this is going to be a dead kid sobfest," I said, "I dunwanna read that."

But I kept going! And it was not a dead kid sobfest, and it was not "I am riddled w ennui shall I cheat on my wife perhaps" like many "A Novel" books. And "unreliable" in this case meant "tells a story" and not "is hallucinating" as it sometimes does. So if you're balking based on any of those, you're clear.
