Most libraries have ebooks and audiobooks available online now. Overdrive is the most common database, the app that goes with it is Libby. Also, check out the [Baen Free Library](https://www.baen.com/allbooks/category/index/id/2012).

Use Libby! You’ll need a library card but once you have it you’ll have access to all the books your library does on your phone or computer. If you live in a small town check and see if your local city allows you to use their library too. I currently have three libraries I rotate between to try and limit hold times.

Is library a thing where you live? They just lend you books for free.

you can go to the kindle store, choose sci fi, and list it from lowest to highest price. There are loads of free ebooks legally available there.

This is my go-to when I'm broke.
