The Artificer #9

Keys Between Worlds (The Artificer Book 9): A Portal Progression Fantasy Series

Rate this book
The artificer has no client this time—and the stakes are far higher than usual. A friend must be saved.

The trail leads into disputed lands, home to an ancient people—ruled by unfamiliar magic, riddled with anomalies, and brimming with discoveries no one expected. The final pair of magical aspects marks the start of a much longer journey. And the rescue mission is no longer just about saving people, but entire worlds. At least, that’s what their inhabitants claim…

Yet no challenge is impossible for Count Voznesensky—even the completely unexpected kind. On the contrary, he finds it more exciting this way!

kind of a “plain” story this installment

It was good. Alexander ran around a lot. Not as well written as previous books. Adventurous it was not. Exciting it was not. It was a lot of assumptions-assuming what people did and thought. Both past and present.
I will be reading the next book. But I was disappointed.

My reviews are my own. If you enjoyed this book, I’m glad you did. If not, I respect your opinion, so please respect mine. This is simply my view, so let's keep it courteous. My review is honest and voluntary.

This book felt completely different from any of the previous ones. There was barely any meaningful artificing at all, and I honestly kept waiting for the point of the story to reveal itself. Maybe this is one I need to reread, but by the end I was mostly confused about why it even exists within the series. It wasn’t bad, but it felt disconnected — almost like a completely separate story awkwardly attached to the existing narrative.

What frustrates me most is that there are still so many unfinished plotlines and unresolved topics from earlier books, yet this installment sidelines all of them in favor of strange new side stories. It feels like the original heart of the series has been forgotten, and now the focus is on stretching things out instead of meaningfully continuing the story.

If the author wanted to introduce another world or a new concept, that could have worked — but dedicating an entire book to it while ignoring everything readers were already invested in was a huge mistake. This honestly felt less like a natural continuation and more like a book written because another release was needed.

I’m genuinely disappointed I preordered it, and this is the first time in the series that I’m seriously reconsidering continuing it.

On to my next adventure, Happy Readings!!!

engaging series

I enjoyed this volume as much as the earlier ones. I like the approach of each issue not being almost impossible to handle. I look forward to where he texted the development of the main character in his future books..
