I’ve heard authors ask, “Should I write a series or a standalone?”

My first answer would be to write the story in your heart. DO NOT WRITE TO TRENDS – say it with me. Do not. By the time that story’s written, revised countless times, edited, and polished, that royal Tasmanian zombie-shifter prison quartet trend will have flashed and died.

But if you can see your story going either way, here are a few truths regarding series and standalones.

• Historically, authors are told to write series. Series sell better. If you’re shooting for traditional publishing, it shows agents/publishers you have more than one book in you. Readers like following characters they’ve read about before. (This last point is a double-edged sword. More on this later.) But if there isn’t an arc there, and you aren’t interested in adding or fleshing out secondary characters, don’t force it. Some stories might only be one book long. That’s not a crime. In fact, lately, I’ve hesitated to buy or read a book in a series. Every story seems to be part of a series (says the author who wrote a trilogy. Ahem.) Sometimes I just want to read a well-told, juicy standalone. Sometimes I just want to write a well-told, juicy standalone. But…
• There’s a benefit to sticking with characters you’ve created, tortured, and triumphed with after just one storyline. I found this especially true with the Firebrand Chronicles. I grew to really know and love Brenna, Baldwin, and Arvandus. Spending all that time with them made me imagine what else could happen to them. After finishing a story, I usually imagine different connecting points between characters and plot. Even my short story “Everwild” (which is in the anthology Mythical Doorways and is FREE, BTW…) is already a four-book series in my head. I have plenty of adventure and mayhem planned for half-fae Flint and full-fae Lila. I just can’t get all my projects written as quickly as I’d like.
• At the outset, writing a series requires more planning. Detailed notes are imperative—a “bible” for your world, with the characters, their backstories, descriptions, towns, magic system, tech level, money system, languages, belief systems, etc. You won’t remember it all—trust me. Take copious notes and keep them with you while you write. A map is good too, even if it’s one scrawled on notebook paper (which is what I have for my current WIP. I’m not crazy about it, but it’s working—for now.)
• Over the long haul, world-building is generally less work. Although there are detailed notes being listed in your notebook bible, you create one world. That world lasts for the duration of the series. For each standalone, the author must create a new world. Every. Single. Time.
• I mentioned how much readers like following characters they’re familiar with. I’ve found some readers don’t want to buy a book and then wait a year for the next installment. So they’ll wait. (*Raises hand.*) Many will wait until all the books are out. You won’t see sales. Don’t let that discourage you. Keep writing the next story. If you’re self-publishing, you could avoid this problem by doing a rapid release (which is writing all the stories, editing and polishing them, and then releasing them in quick succession, usually no more than six months apart.)

Don’t feel you have to create a series if it’s not in you. There’s a place for everyone at the table, both series writers and standalone authors.
