I've been traveling throughout SE Asia for the past few months which requires long flights and bus rides. I just finished up The Martian by Andy Weir and read by RC Bray, and am about 1/3rd the way through Project Hail Mary, also by Weir and narrated by Ray Porter. Both are fantastic if you're in to hard science fiction. Also, I think the choice of narrator makes or breaks whether or not an audiobook is good. In both audiobooks, the narrator has done a great job keeping me captivated with the story.
