This came up in a different thread, and I thought it might be good to explore the idea a bit: Do publishers want debut authors to stick to stand-alone books, or are they also looking for series? This may come down to how we define 'series'. Is it a set of books that have one plot, each book ending on a cliffhanger, or is it a set of books in the same universe and probably with the same characters, working on some over-arching goal but resolving smaller conflicts within each book, so that each book COULD function as a standalone? In my experience (and my genres - romance and YA romance) publishers are actively looking for books that fit the second definition of series. In two cases, my agent submitted a standalone novel and the acquiring editor came back with an expression of interest in a series. I have other books published under a different pen name, but these would be my debut books under a new pen name. But others are saying that it's very difficult for a new author to sell a series, and they should stick to standalones. Does anyone have any evidence/experience to back this up? I feel like I see new authors writing series fairly often, but maybe they're the exceptions that prove the rule?
