I've put together a collage of some books from last months What are you Reading? post. It's mostly random, but the more discussion something gets the more it stands out to me. Going forward I'm going to make a new post every month to talk about what people are reading.
Andy Weir's second best book after "The Martian" in my opinion. But not by far, it was a great read and I enjoyed every page of it.
Rocky for intergalactic president!
I liked the bigger scope of PHM, but Weir is Weir and great. It's like going to an amazing homemade ice-cream stand. You might like vanilla caramel, and your friend might like the strawberry chocolate, but you're both just happy the place is open.
I made a kind of "if you like PHM you might like these other books" rec chart thing when I first read PHM; if you've finished reading it you might enjoy some of these (although it does mention a few key elements of the book so if you're going in completely blind and aren't far in yet then don't look at this yet).
