title_body: Share book uploaded to my Google Play Books account with other account I uploaded a book to my Google Play Books account and I want to share it with another account, is that possible?
  I know that I can give it the .epub file but I deleted it.
upvoted_answer: As long as you uploaded that specific book to google play books (in contrast to buying it on that platform) you can simply download it as a epub/pdf file using Adobe Digital Editions.
  A detailed tutorial on this procedure can be found at Google Play Help.
