The only one available so far (and quite thorough) is Mastress Alita's summaries, which have been posted in this thread.

Those summaries aren't complete for she's halfway through the series and is apparently lagging for Part 10 (in other words, the anime is catching up to her). However, since the timeline is being warped for the anime staff's convenience, what you can read there are still accounted a spoilers...especially since you'll see two individuals that should make their debut in the yet unaired EP16.
I just hope she'd find enough time to finish Part 10 and give us more. You can read the whole story like a novel, that way.
