My book, TRANSPARENT, doesn't have a sequel currently.
I have noticed a few instances where my book has been referred to as a series because I happened to sell two books. But that's not the case. The second book HarperTeen bought from me is an "option." It could be a sequel to TRANSPARENT, but it might not be one, too. It might be something totally different. And guess what?
I'm okay with that.
I wrote the book to be a complete story. Of course there could be more story after, just as there could be more story before. That's the thing about stories—they never really end. You pick a good starting spot and a good ending spot, but if your characters are solid there will always be more to tell.
So where do you stop on the sequel train? Or do you even get on in the first place? I don't really know. You see, I'm not completely against writing a sequel either. It could go either way in my mind. It's not as if this is my only idea for a novel. I, uh, tend to have a wealth of ideas, so maybe I am the ideal writer to go the "Killer Standalone" route. But at the same time, there is definitely more to explore in TRANSPARENT's world, more for Fiona to learn and discover. I guess I'm lucky my publisher will just tell me if I'm writing one or not, heh.
But overall, I think sometimes we get attached to the idea of writing a series (At least I know I was violently attached to it at one point). We want to stay with the characters we love and know just as much as we hope readers will. Though sometimes it's better to leave a reader wanting just a little more than you gave, instead of giving more than they ever wanted.
I don't know, I'm kind of digging the standalones these days. I think YA could use a few more. I wouldn't mind being in that category.
