More from S.F.

Stolen Secrets is the seventh book in the Mirror Estate series, and for me it represents something I didn’t fully realize when I started writing it: the beginning of the end of the Ghost arc.

When I began the series, I never mapped out a long, eight-book storyline for the Ghost. In fact, I didn’t even think about how long that arc might last until around Book 6, Shadowed Secret. That’s when it started becoming clear that the threads surrounding the Ghost, Dylan, and the larger conspiracy needed more room to unfold. Book 8 will wrap up the Ghost storyline, though the Mirror Estate series itself is far from over. There are still many stories left to tell.

One of the continuing mysteries involves Dylan and the buried treasures connected to Mirror Estate. Whether that storyline concludes in Book 8 or continues beyond it is something I’m still discovering as the story evolves.

Stolen Secrets also includes a bonus story titled “Shadow Extraction.” Writing that novelette was one of the hardest parts of the project. It features Olivia in the middle of a black-ops mission that unfolds at the end of her honeymoon in Italy. The emotional and operational stakes in that story made it especially challenging to write, but it also became one of my favorite parts of the book.

Another element I enjoyed writing in Stolen Secrets involves Jamie Beth and Owen. Watching those two characters work their way through danger and figure out how to escape was incredibly rewarding as a writer. Those scenes capture something I love about thrillers—the moment when characters must rely on their own courage and quick thinking to survive.

Looking back, Stolen Secrets feels like a turning point for the series. Secrets are beginning to surface, alliances are shifting, and the long game surrounding the Ghost is finally moving toward its conclusion.

But even as that arc approaches its end, the world of Mirror Estate still holds plenty of secrets waiting to be uncovered.

Author Interview

• What is your favorite genre of books? Why?

Crime thrillers are my favorite, hands down. I don’t know that I can give a deep reason for it. I just love the thrill of following investigators as they work to solve a crime. There’s something about that tension, that puzzle, that keeps me completely hooked from the first page to the last.

• Are you a one project at a time author or do you have multiple projects going at once?

I focus on one project at a time when it comes to the actual writing, but I’m always planning ahead. Several projects tend to be taking shape in my mind simultaneously. It’s more of a pipeline than a single track. That way, when one project wraps up, the next one is already waiting.

• Where do you find your greatest inspiration?

Crime TV shows are my prime source of inspiration. I love losing myself in a good series, and those stories have a way of sparking ideas I couldn’t have come up with on my own. The way investigators think, the twists, the stakes, it all feeds directly into my writing.

• Who is your favorite author? Why?

Honestly, I like too many authors to single out just one. Picking a favorite would mean leaving out too many writers I genuinely love, and I’m not willing to do that to them or to myself!

• Do you have extensive outlines when writing or do you write a book as you go?

Somewhere in between. I start with a rough outline to give myself a roadmap, but I stay flexible as I write. Sometimes the story wants to go a slightly different direction, and I’ve learned to let it. The outline keeps me grounded; the tweaks keep it alive.
