Thanks for all the welcomes
Yes Indie = self-published. In the world of Ebook sales, self-published authors are popping up daily, promoting their books at Amazon and on some ebook forums I frequent.
My favorite indie author has been Boyd Morrison. I guess I should say he's a "has been" as he has been picked up by a publisher. He offered his three books for free at Amazon and I had a backlog of ebooks so didn't get around to him recently. When I did read them, I was quickly caught up in the action and enjoyed them all immensely. Here is a link to his site--you can see the synopsis of his books--they are all action stories based on science.

On Amazon, you can sign an agreement and upload your ebook. It is cautionary--there have been some stinkers, but I have found more that I like than not. Many of them have the books at .99 cents or less so it's not like I lose anything by trying them--delete is always available.
