Souls of Fire Books in Order

Souls of Fire is one of Keri Arthur's best blends of modern urban fantasy, hidden-world suspense, and end-of-the-world science gone wrong. The heroine, Emberly Pearson, is a phoenix who can take human form and who carries a terrible extra gift: she can foresee death. That one detail shapes the whole series, because it means every case is haunted before it even begins.

Emberly sees trouble coming.

The world of these books is also slightly different from some of Arthur's others. Vampires and werewolves are public knowledge, but a lot of the rest of the supernatural world still prefers to stay out of sight. Emberly is part of that hidden edge, and she would like to keep it that way. But Fireborn does not let her. A vision leads her back to Sam, a man she once loved, and what follows is the discovery of the Crimson Death, a plague-like virus born from a failed government attempt to isolate the secret of vampire immortality.

That virus becomes the big thread running through the series. In Wicked Embers, Flameout, and Ashes Reborn, Emberly and her partner Jackson Miller keep chasing the stolen research, the people weaponizing it, and the fallout spreading around them. Arthur uses the outbreak structure well. There is always another reason to hurry, another body on the ground, another piece of evidence that the people behind this are thinking bigger than one city or one target.

At the same time, the books stay personal. Emberly is not a faceless action lead. She is pulled between old loyalties, current partnerships, prophetic visions, and the limits of what she can save. Jackson gives the series its strongest emotional counterweight, but Sam and the Paranormal Investigations Team keep making the lines between ally and complication blurry.

The tone is darker than cozy but not hopeless. These books like murder scenes, monsters, betrayals, and desperate choices, yet they also move quickly and keep the emotional stakes clear. Emberly is always balancing the same question: how much of herself can she risk in trying to stop the next disaster?

There is also plenty here for readers who like a broader supernatural mix. Phoenix lore sits beside vampires, werewolves, witches, and government experiments. Arthur makes that combination feel natural by keeping the story tightly focused on the investigation and on the consequences of failure.

That is what gives the series its heat.

Not just romance, though there is some of that, but urgency. If you want Arthur in a mode where every clue matters, every dream might be a warning, and the central threat could genuinely change humanity, Souls of Fire is a very good fit.
