My Thoughts on Shadowed Secret

It’s a fast-paced novel that you’re not going to be able to put down! Seriously, who has heard of a Navy SEAL turned priest!? And when he’s sent on a mission to find a book before the bad guys get it you know it’s gonna be filled with suspense and danger and maybe even a bit of humour too.

This book is part of the Mirror Estates series. And yes, it’s a series, so yes, you need to read the books in order. While you might be able to read this novel on its own, you won’t have any of the backstory. Just do yourself a favour and grab the entire series to read start to finish.

There are so many twists and turns in this novel. I truly loved all the suspense and watching the plot unfold and then twist around so that you had to keep guessing about what was going to happen. I highly recommend this novel and the entire series. You will not regret reading them.

Unraveling Secrets: The Journey of Writing This Book

Some books come together effortlessly. Others take their time, demanding patience, persistence, and more rewrites than I care to admit. This latest instalment falls firmly into the latter category. The story simply didn’t gel the first couple of times I attempted to write it. I knew where it needed to go, but the journey to get there felt off. Characters resisted the paths I initially set for them, subplots unravelled at the seams, and the pacing never quite clicked the way I wanted it to.

It took several drafts and a fair amount of frustration before things finally started falling into place. Looking back, I realise that part of the struggle was that this book needed to do more than just continue the story—it had to weave together past threads while setting the stage for what’s to come. That’s a delicate balance, and it wasn’t something I could rush.

Why I Wrote This Book

The simplest answer? It’s the next chapter in the story. After everything that has happened in previous instalments, there were lingering questions that needed answers, loose ends that needed to be tied up—or, in some cases, unravelled even further.

This story is about Fr. Phil.. He’s no longer just the priest of Mirror Estate’s chapel; he’s once again being pulled into the shadows of his past. Old alliances resurface, and new threats emerge. At the same time, Olivia and Simon’s upcoming wedding adds a deeply personal layer to the story. In many ways, this book is about past decisions catching up with the present—whether in matters of faith, espionage, or personal relationships.

And then there’s the Ghost. Marge Beaumont remains as enigmatic as ever, and while she’s playing by the rules—for now—it’s clear she’s still ten steps ahead of everyone. The question isn’t just whether she can be trusted, but whether anyone can truly outmanoeuvre her.

The Challenge of Getting It Right

What made this book particularly challenging was the complexity of the narrative threads. There’s a missing book that may or may not contain dangerous secrets. There’s an auction on the dark web that threatens national security. There’s a decades-old mystery involving hidden treasure. And, of course, there’s the ever-present undercurrent of trust and betrayal—who’s telling the truth, who’s working an angle, and who’s about to make their next move?

Balancing these elements while keeping the pacing tight and the stakes high took longer than expected. Some subplots had to be reworked entirely, others had to be trimmed down, and a few surprises emerged that even I didn’t see coming in the early drafts.

What’s Next?

Now that this book is finally complete, I can say with confidence that the struggle was worth it. The twists, the revelations, and the character moments that emerged from this process have made it stronger than I initially imagined.

For readers who have been following this series, I hope you enjoy the ride. Expect high stakes, hidden agendas, and a few moments that might just leave you breathless. And as always, thank you for sticking with me on this journey, because the story is far from over.
