If you choose the book first maybe its better look writer website first where it is available. I have a pocketbook reader, it doesnt work very well with kindle books, when I was searching Wheel of time and Brandon Sanderson it was available on google books as DRM free but it was the choice of writer. So when you are looking for books there, you need to check first if there is a 'DRM free' flag.
