yeah godheval's advice is pretty sound if there are enough reliable sources to warrant a separate article go for it if there is only a little information about the series out there compiling it into a single article may be the best bet it's really up to what you think would look best generally if there are at least a couple of sources like reviews or news stories about the book then a separate article works best i know nothing beyond the series beyond the basics i work in a bookshop so i can't really give an opinion on this series specifically at the moment i'd be happy to give my opinion on help improve an article if you write one
