Want signed copies of The Expanse books? Well minus the last (book 9) which has yet to be released, and the in between novellas.
If you weren’t aware, the 2 authors that make up the pseudonym James S. A. Corey were members of George R. R. Martin’s Sante Fe, New Mexico writing group, and one of them was Martin’s executive assistant. So these are legitimately signed by the authors and specifically assigned for sale by Martin’s sci-fi/fantasy Santa Fe movie theater/art gallery/book store.
