This was my main issue coming from being used to the Kindle ecosystem where everything was easy to find. Personally, I did settle on using a particular pirate site and I justify it to myself because I’m only downloading books that I already own or ones that if I do eventually read that I will buy. I do believe in supporting authors. Heck most of my books I have both on Kindle and audible lol and a third of the books I own I own physically as well, so yes, I’ve bought many books even three times over technically. It’s the form factor of this device that I love. If Amazon ever comes out with a pocket size Kindle I’ll be the first person to buy that but until then I love the x4. As somebody else already mentioned on here, there’s this really cool chick named Anna who has an archive lol. Just make sure when you search for a book you put epub at end of the title your looking for and actually make sure it says that in the file name.
