I thought Ken Liu’s translation of Three-Body Problem was superb — I read a couple of his other translations since (Invisible Planets, Waste Tide). The Dark Forest is a different translator, it was a bit of a chore for me but had its moments. I wonder how much of it has to do with the translation. They went back to Liu for the third book, which I haven’t read yet.
FWIW I really liked Big Swiss. Not in my favorites of the year, but solidly entertaining. I thought the transcription sequences were inventive and memorable (the main — not titular — character is a stenographer for a therapist), where she’s typing out recorded therapy sessions and reacting to them. I think it’s a pretty “New York” book though, for anyone who’s lived in the city and spent time upstate. The setting — Hudson, NY — was really its own character for me. I can definitely see it being not for everybody.

Ditto what someone else said here. Find the best nearest used bookstore and trade em for store credit (most stores will give more credit than cash). Turn old books you won’t re-read into new or new to you ones that you will. That’s what I do.
If you don’t want to go that route, there’s an app called decluttr, you scan the barcodes or enter the ISBNs, they quote you a price, send you a shipping label to mail to them, and paypal you the money when they receive.
