The first time I read this book, I was... oh, about ten or twelve. It came in a large pile of five-cent books at a flea market and was missing both the covers, so I had no idea what I was getting into when I opened it. All I knew was that it said "Tomorrow's Sphinx" on the spine, with this itty bitty icon of a black cheetah face with gold tearlines, and a gold pharaoh's burial mask.
I read it once. Loved it. Read it again, still loved it. Moved, lost it, moved, found it, moved, lost it... I'm twenty one now, found it again, and read it again. I still love it, though not as much as I did when I was a kid.
It's frustrating at parts because I'm old enough to over-analyze it. I try a little too hard to figure out exactly what it is that's being described; but a cheetah that's never seen a two-legger or their machinery before, is not going to have a word for propellers or wheels or any other artificial things, so it's a rather pointless endeaver to try and figure out if that "shiny giant not-a-bird thing" is a plane, or a helicopter, or a flying saucer. If you can just sit back and enjoy the narrative without trying to make everything fit into a template of your own level of knowledge understanding, it'll go much easier.
The info-dump at the end could have been handled better, but the story itself is still a good one. The characters are very good, the mythology is great, and the chance to look at the world through the eyes of a sentient animal is still something I greatly enjoy.
I highly recommend this!
