I have read two of the three body books, but I wasn't aware of a sequel to project hail mary, would be very excited if that's the case!
It was just recommended to me by someone, but I'm usually into sci-fi, stuff like Greg Egan.
I really enjoyed it, but maybe I would have been disappointed if I was expecting more of a mind melter!
yes, the writing was annoying in parts (especially the Earth flashbacks). What I liked about it was 1) if you don't know anything about it (I didn't even read the back cover) the surprises evolve nicely; and most importantly, 2) it was a story of humans cooperating with another species rather than either subjugating or resisting subjugation
I hadn't read any Andy Weir before, but someone recommended it to me so just started reading.
My favorite is probably Permutation City, followed by Diaspora. His stuff can get heavy though.
Though I can't say much without giving away spoilers.
A great read if you are a sci-fi fan!
