American Gods was designed to be if not open-ended, at least a trilogy kind of shape, so there's definitely one more book, probably another couple of books there to get written.
Neil GaimanWe writers โ and especially writers for children, but all writers โ have an obligation to our readers: it's the obligation to write true things, especially important when we are creating tales of people who do not exist in places that never were โ to understand that truth is not in what happens but what it tells us about who we are. Fiction is the lie that tells the truth, after all.
