This is my opinion. After publishing two books with iUniverse, I can only believe I made them a lot of money which they did not pay me royalties on.
I know people are buying them. I get reviews, hits on my facebook pages etc..., yet the royalty payments do not match the level of interest. It would cost me a fortune to hire an attorney and push for a full audit of this companies books, something I'm unwilling to do because despite the fact I believe they owe me money, I can't be sure that money would cover the legal fees.
What I will say is author beware. Proceed with caution.
