Sea of Tranquility (2022) by Emily St. John Mandel. Best sci-fi novel I've read in I can't recall how long. Outstanding. Mention it here because it involves a writer and extended hyper-realistic sequences of book signing tours. Time traveling, Vancouver Island, lunar colonies, pandemic (not in our time), Oklahoma. By a writer who has certainly done book tours herself, having written a couple earlier well-regarded novels. I may get to those one day.

E. Writer I will have to check it out one day. I've read a lot of great sci-fi by writers i know that are among my favorites but thos will sound silly, but one of the best science fiction novels I've read is Revenge of the Sith by Matthew Stover. The novelization of the Star Wars movie. Beautiful job he did with the writing.
SJ Blues I am intrigued
