THIS!!!!

It's funny you brought up Project Hail Mary because I actually did what OP mentioned in the post with that book but Artemis by Andy Weir I FLEW through that book. I absolutely needed to know what happened next. I finished that book in a couple of days. I would always think to myself "maybe I'm reading this too fast" but I just... never put it down.

I always try to finish at least a chapter before I set the book down for any period of time. Mainly because it's easier to jump back into the book when I pick it back up. But you bring up a good point of thinking about it before starting the next chapter. I'm low key doing this every time I put down a book. The main book that really comes to mind that made me stop between each chapter and take a breather or really think about what I had just read was the first Dune book. It's a book I try to reread at least once a year, but damn, that first time it took me forever to finish just because there was always so much to digest and think about.
