I almost DNFd one of my most anticipated books of the year. After reading The Martian and Artemis last year, I was so ready for another fun Science-fiction adventure by Andy Weir. Except this one was way more science than fiction, and given that I know absolutely nothing about physics or biology or any scientific stuff, I didn't enjoy this book much. I'm really frustrated because this title keeps cropping up in people's favourite books of the year. I just wish it had been like that for me. The hero felt like a pale copy of The Martian's Mark Watney, like the rest of the book. A lot of the plot twists felt similar, which is regrettable when your opening scene has a (white) man alone in space, except that Ryland Grace, in PHM, has the fate of the world in his hands, not just his own fate. I could see there was a great story unfolding, which I won't spoil you, but it didn't excite me or move me. Aaaargh. I'm frustrated.
Rep: it's never said, but the main character could very well be aro/ace.
