I now have 6 books for sale in Google Books/Google Play. I still think their interface can use some work, but when everything is exactly right (all the fields are filled in, the cover and book/epub file have been uploaded) it takes seconds for Google to process a book for sale. Amazon and Barnes and Noble both take hours.
Book 7 will be along shortly. My husband is home form the hospital, but he still needs a fair amount of help.
