Similar to the Bobiverse, where he has to come to grips with his new life, I'm looking for books where the Protagonist is a fish out of water in his environment.
Books I've read that kinda match the vibe (to at least some degree):
The Martian
Project Hail Mary
Starter Villian
Old Man's War series
The Bobiverse
