Most people are giving great recommendations for general astrophysics/cosmology books, so I’ll go a different direction with space exploration history /engineering.

The book “Failure is Not an Option” by Gene Kranz is an autobiography from a NASA flight director who was in Mission Control for Apollo 11 and 13 and documents NASA history from Mercury to Apollo. It does get very technical and nitty gritty but it’s a great read and lets your realize just how complex space exploration is.
