Use the Promo Code: BELULUS and get 28% off you order from Lulu.com! This is a deal on physical copies of City at the Top of the World and any other stuff you might be wanting from Lulu. City may not be up for a Hugo, but you won’t hate yourself for reading it, guaranteed!
Also, why not check out Dyson’s Delves while you’re at it? I’m not an affiliate (so I don’t get any money from it) or patreon or anything, but 90% of the time I come across Lulu promo codes, it’s because Dyson’s the one sharing them.
