Kobo with KOreader is a great option. KOreader can connect to your WiFi and you can rsync your library to the device.

Imagine going on the piracy Lemmy community and preaching the moral wrongs of copying.

Seriously though, DRM is a cancer. I usually pirate my books from LibGen, but I buy them on the Kobo store at the same time to support the author. It’s easy to strip DRM from Kobo and they’re better than Amazon, but I would really prefer not to support a store with DRM in the first place.

Can anyone recommend a DRM-less store? Something akin to GOG for books.
