Good Memorial Day sales, need suggestions for books to pick up.

Not sure if I'm allowed to post who is having a sale. But popular used bookstore near me is having a buy 5 get 5 free (for fiction) sale. And boy do the wife and I love to support them.

Problem is I'm running out of books to look for. Please suggest any fiction books you've loved with a small description. Looking for older more obscure works but welcome any and all suggestions.

I personally like sci-fi (which might not be included but would love more for later anyway) and fantasy. Favorite Authors right now are Neal Asher and Robin Hobb.

My wife is a "bookstagramer" and I admittedly have a hard time keeping up with her favorites. She loves YA and Distopian / end of the world. Recently read Aura Rising and loved that book. Also loves the retellings of classical works.

Thank you all :)
