I’m in the middle of writing my fantasy series. My first book is a novella at around 30,000 words (when I’m done editing it’ll probably be near 40,000) and right now I’m writing the second book. From the amount of things going on in the sequel and the current word count of some chapters, I think it will end up becoming a short novel (at least 50,000 words) instead of a 40,000 word novella.
To all those who write series (or read series) should the length of each book be uniform, or can some be shorter/longer than the other? I’ve seen series where it’s either all novels or all novellas (and for those that mix, the novellas aren’t direct sequels to the novels so they act more like companion books). I’m asking because I don’t really want to stretch my first book, but at the same time I can’t cut down on my second book.
EDIT: Thank you to all those who responded! I guess varying word counts are okay.
