I second Libby. You can get just about any of the books recommended on this thread for free. Additionally, for me, I like to get my books from the library since it gives me a reason to read them before I have to return them.

I have not tried Libby yet but recently started checking out eBooks from my local public library (via Overdrive) to read on my Kindle. I am pleasantly surprised how convenient and straightforward that process is. And all that without spending any money.

Libby is the new and somewhat flashier version of Overdrive. My old Android tablet doesn't handle it as well as the old overdrive app, but it works. I think it also has better support for multiple library cards than overdrive, but I haven't tried that yet.

I've used overdrive with 2 library cards and never had any issues.

I really don't understand the need for libby

I've not tried Libby yet, but I always find the popular books on LibGen.
