Avoid buying books written after 2022.
For Rust specifically, the official book should get you up to speed. There's also Rust by Example. If you want to get into unsafe, the Rustonomic is good. Rust Atomics and Locks, if you're into low-level stuff. All of them are free, by the way.
Also, might be controversial, but you can just pirate books you aren't sure about. If a book turns out to be good, then buy it to support the author.
