It would seem that you're one of the few here with direct experience.
1) Did you sign your copyrights over to Rain publishing?
2) Did you pay them any money?
3) Did you receive an advance?
4) Have they distributed hard copies of your book to bookstores?
If the answers are --
1) I hold the copyright. They have first North American Publication Rights only.
2) Not a penny.
3) $2000. and
4) The books are on the shelves of Barnes and Noble right now.
Then I'd say you've signed with a good small press.
It's not all that hard to tell a small press from a scammer. You look which way the money flows.
1) I signed a contract that was examined by my agent. There were aspects of it that he wasn't entirely comfortable with, but not to the point where he said it was a deal-breaker. No company can do absurd things in their contracts and expect them to stand up in court.
2) Not a penny.
3) I was paid no advance. But is that so unheard of in this day and age, when first-time fiction is such a difficult sell? How many of you out there remain unpublished, despite being talented?
4) Book One of my series debuts in September, so at this point it's not on any bookshelves.
All I know is, I have thus far been treated with professionalism and respect by Rain. Would I have preferred to sign a mega-deal with a huge publisher? Of course ... I'm not an idiot. But I have no previous novels to my credit, and on top of that the fantasy market is glutted. So I did the best I could. In my opinion, Rain is a legitimate small publisher -- not perfect but not in any way sinister or crooked. In the beginning, my agent was lambasted in this same way. But he was legit then and he is highly respected now. I see Rain going in the same direction. And if not, what would you have me do? I'd rather be published than not published. At least it gives me a fighting chance.
