Going to have a ton of down time due to some upcoming surgeries and would like to catch up on some reading. Have a ton of books on Kindle but the formatting options for that platform sucks. Have downloaded a few "free" converters on to an old laptop to check them out but they also installed so much bloat/spy/malware that I'm going to have to reformat the drive to get rid of it all. Willing to pay a few bucks if necessary for something that works without too much hassle. Whap program(s) have you used and recommend? Thanks!
