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.

My Impressions

“Every family had secrets. Probably hers too. She was adopted. That alone meant there was a whole history she didn’t know. A mother. A father. A reason they gave her up.”

I hope I can sleep tonight! I just finished Stolen Secrets, #7 the Mirror Estate series, by S. F. Baumgartner. The novel is touted as a thriller. I had forgotten since the last book just how thrilling, in chilling way. We are following the story of the Ghost, an infamous criminal who is now cooperating with the FBI and CIA. For unknown reasons, the Ghost has decided to help protect 17-year-old Jamie Beth O’Roarke. Jamie was adopted at 5 years old by Charlie and his wife, partly as their answer to prayers and partly as an assignment. “Are you asking me to help you disappear a child?” “I’m asking you to help keep one alive.”

When a friend is mistaken for Jamie and kidnapped, events are set in place that interconnect. Rescue and intelligence-gathering operations are detailed and complicated. And my eyes were absolutely glued to the pages as I read! I could feel the tension, the terror, the confusion, every emotion Jamie and Owen felt as well as those of their parents and all the agents involved in this case. I loved seeing the creativity of Jamie and Owen when the cards were stacked against them.

I was very grateful for the opening pages of the book. Each previous book in the series is summarized. Even better, there is a relationship chart that takes up two full pages. I took pictures and referred back to the charts frequently as I read to get a clearer understanding of all the moving pieces in this story. Plus, there is a map at the beginning of the book. Kudos, Ms. Baumgartner!

If you love exciting action, multiple characters, rapidly changing scenes, and a complicated mystery, this book and series is for you! I can’t wait for the next book and more of the ongoing mystery to be solved!

I received a copy of the book from Celebrate Lit. I also bought my own copy. No positive review was required, and all opinions are my own.
