Developmental Editor for Speculative Fiction

Writing a novel is a journey, and every great journey needs a guide. That’s where a developmental editor comes in. Whether you’re crafting an epic fantasy adventure, weaving a science fiction saga, or diving into the depths of romantasy, I help authors like you bring their stories to life with professional editorial services tailored to your unique vision.

I am obsessed with stories.

Fiction has the power to shape perspectives, challenge ideas, and leave a profound impact on readers long after they’ve turned the last page. This led me on a quest to figure out why certain stories stayed with me years after I put down the book and why some didn’t resonate.

Determined to uncover those secrets, I began training with the Editorial Freelance Association, diving into every craft book I could find. Then, it all started to click…

Studying the art of storytelling helped me finally understand what makes an unforgettable novel.

Now, as a developmental editor, I use that knowledge to help authors like you craft stories that captivate readers from the very first page.

I’d love to help you build a novel that feels just as gripping as your favorite books. Check out my services page to learn more!

Maine

I live in Maine with my fiancé. We love hiking and exploring!

Books

No surprise, but I love books. As a kid, I even stole my siblings’ library cards just so I could check out more of them.

Honey

My Springer Spaniel is my assistant… but, let’s be honest, she’s not very good at it. Probably because she can’t read.
