PESTILENCE
Book One of the Undone Series

Aiden Blackwell was born in Salem in 1684.

For more than three centuries, he has hunted the monsters that hide behind religion, myth, and fear—mages drunk on power, demons wearing human skin, and the celestial beings who call themselves angels.

He is known by only one title.

Battlemage.

And now, he has discovered how to end them permanently.

When a mysterious plague begins tearing through Boston, killing indiscriminately and spreading faster than science can explain, Aiden recognizes it as something far worse than a disease run rampant.

Something ancient.

Something biblical.

As entire cities begin to collapse, Heaven moves in the shadows, demons make their own bargains, and God Himself begins setting the stage for a new kind of domination.

When Aiden is hired to find a missing boy whose disappearance may be tied to the outbreak, the investigation pulls Dr. Evangeline Tucci into a world she was never meant to see.

A skeptical CDC virologist, her existence should be impossible—a woman untouched by magic in a world unknowingly bound by its rules.

With the help of Rafael, a centuries-old inquisitor who once spent his life hunting men like him, and Ash, a foul-mouthed fallen angel, Aiden must uncover the truth before the boy—and the world—run out of time.

Just finished reading Pestilence by Donald R. Blackmore, and I have to say—I was genuinely impressed. From the very first pages, the story pulls you in with suspense, tension, and a sense that something bigger is unfolding beneath the surface. Blackmore does a great job building atmosphere while keeping the pacing strong, making it hard to put down.

What stood out most to me was the way the book blends gripping storytelling with thought-provoking themes. The characters feel real, the stakes feel high, and the story keeps you fully engaged from beginning to end. If you enjoy books that are intense, immersive, and leave you thinking after the final chapter, this one is absolutely worth checking out.

Congratulations to Donald R. Blackmore on a fantastic release. Looking forward to whatever comes next.

Fun dark fantasy

This book had me curious from the first few pages. What New Englander can resist something that starts in Salem, MA during the witch trials? Though, that isn't expound upon (at least not in this first book) we quickly get thrust into the beginning of the apocalypse and familiar religious characters.

The characters were great, I especially loved Ash, the fallen angel, and all his witty snark.

Making the side of heaven look less than benevolent was a great choice, making it less a difference of good and evil and more two powerful sides looking out for their own interests.

Aiden, our main character and Battlemage, seems to be kept at a distance. We don't really get a close feel for him. I assume this is intentional as it mirrors how the other characters, especially Eva, probably feel twards him. This naturally has me curious about him and I hope the second book dives deeper into what makes Aiden tick.

I'm not much of a fantasy reader but make it dark with twisted religious ideas? I'm in! This was very fun and I'm excited for book two!

Before you know it you're hooked and somewhere chest deep amidst the story. This read absolutely flew by and both ended satisfyingly and left me hoping for more.
Lots of unique characters both lovable and otherwise and a storyline that just pulls you smoothly along.
