If you’re looking for software related ebooks, I’d really recommend the Pragmatic Bookshelf: https://pragprog.com/support/ https://pragprog.com/support/ Great customer service, less expensive than getting it from Google play books etc (at least in my case), and DRM-free ebooks so you can copy to your other devices if needed.
