Wanna do me a favor?

I’m looking for beta readers– at least a couple, but a few more is fine– for my novel Skylights, due to be self-published in ebook form in June.  It’s already in pretty good shape, but it wants for one more pass before I push it out to the universe and I figure I might as well have a couple of other folks take a critical eye to it before I release it into the world.

Specifically:  Skylights is a roughly 100,000 word novel (over 400 pages in traditional paperback size) about the first few human missions to Mars.  I’m looking for people who enjoy science fiction, but don’t feel like you have to have everything Heinlein wrote memorized or anything.  I’m asking you to commit to getting the novel read and some sort of written critique (a couple of pages, maybe, and if you like more is fine?) back to me within a reasonable time frame– say, by the last week of April.  For this I will thank you in the novel itself; I’m not actually offering any real compensation.  I don’t need line edits or anything like that; my wife is a former editor and the manuscript should still be awfully clean, although if you find something and want to point it out that’s fine; I’m mostly looking for story-level critiques.

I’m planning on sending out .PDF files, but if you’d like it in some other format we can figure that out.

Interested?  Let me know in comments.  I don’t have any particular ideas for who I want but folks whose names I recognize are a bit more likely to be chosen if for some reason I end up with a ton of volunteers.

Thanks!
