Reading books on the iPhone?

I have an iphone and there are some books I really want to read but do not want that I gave, I just want read on my iPhone. I have two programs, and Kobo Kindle book on my iphone and I found a book I want on the Kindle but as my credit card, calling my direction. Will deliver the book to me or I just read on my iPhone? If they offer is not an application that lets you read a book on your iPhone? Help?
