Cassette Beasts! It's a monster collecting game. It adds a lot to the genre (definitely not a clone) and the music is awesome. It got amazing reviews so I'm not sure how hidden it actually is, but I really enjoyed it!
I'm finally reading The Expanse series, currently on book 2 and really loving it!
While I was waiting for book 2 to become available on Libby I read The Spare Man which I also enjoyed. It was a pretty goofy but fun light read (solving a murder on a cruise to Mars).
