When a young, arrogant celebrity athlete is framed for blowing up the floating Imperial sky-palace, he escapes with a rag-tag bunch of surfacer teens into the planet's crime-ridden slums to bring to justice the Empire's most notorious terrorist — its ruler.

Thanks, Karl! I see what you mean.

When a young, arrogant celebrity athlete is framed for blowing up the floating Imperial sky-palace, he escapes with a rag-tag bunch of surfacer teens into the planet's crime-ridden slums to bring to justice the Empire's most notorious terrorist ? its ruler.

I like it. Actually, I really like it!

I assume the athlete is a rebel and blowing up the palace was no accident. Or was it?

The only thing I feel is lacking is 'the plan'. How should we envisage our hero is going to take on the Emperor? How will his special skills allow him to put this in action?

This action will fill most of Act Two and currently I have a good feel for Act One but after that it feels somewhat open...

I like it, though it's a little busy. 'Young, arrogant celebrity athlete' is just a little too wordy, and ditto with 'a rag-tag bunch of surfacer teens'. If you could cut both down to three words each, I think it would read a lot better.
