If you don’t want any spoilers, the start link is for you. Cold-Morning is an ongoing web serial about globe-trotting not-quite-hero Marcus Summanus and his misadventures with magic, gangsters, and mayhem in the 1930s. It is noir, violent, sometimes sexy, often snarky, and intended for a mature audience. It’s an ongoing story, so it’s best to start at the beginning. Everything will make more sense that way.
