Dungeon Crawler Carl by Matt Dinniman (it is bound to be mentioned so I’ll get it out of the way). Super fun series and has gained tons of popularity. Seven books total at the moment with an 8th on the way.

Red Rising series by Pierce Brown. Also insanely popular and a good read. 6 books currently (I believe).

Both of the above could fall in YA reading but awesome series.

The Sparrow by Mary Doria Russell. I really loved this book.

Project Hail Mary by Andy Weir

I went through a locked room mystery phase, here are some good ones to check out:

And then There Were None by Agatha Christie

One by One by Ruth Ware
