So I'm impressed that you picked such tantalizing books that are all new to me! I've heard of these before and that makes them all the more intriguing but I've not read any of them and all of them are exciting to me. I definitely didn't expect three separate books nor did I expect one so huge as Anathem by Neal Stephenson! Lucifer's Hammer by Larry Niven and Jerry Pournelle and Killing Floor by Lee Child are both exciting. So yeah... I have lots to read now! Thanks ever so much for another lovely exchange!
