Supernatural and Elder Threat Assessment Agency Books in Order

The Supernatural and Elder Threat Assessment Agency books sit in the same wider supernatural world as Austerley and Kirkgordon, but they approach it from a fresher angle. Instead of beginning with seasoned occult troublemakers, this series throws a new protagonist into the machinery of hidden war. In Scarlett O'Meara: Beastmaster, Scarlett learns she carries a legacy she never understood, and from there the ordinary world stops behaving like anything ordinary at all.

Scarlett is the kind of lead who has to grow fast. A relic grants power, darker forces want it, and the only way forward is through a world of demons, agency secrets, and people who already know far more than she does. That makes the book read less like an old-hand procedural and more like a supernatural initiation story. You learn the rules of the hidden conflict at the same time Scarlett does, which keeps the pace brisk and the stakes personal.

This is urban fantasy with teeth.

Another nice touch is that the series connects back to familiar faces from Jordan's fantasy side, especially Calandra, the Ice Maiden. That link makes the agency feel larger than a one-book gimmick. It suggests a whole secret British structure set up to deal with creatures, relics, and elder threats before the public has any clue they exist. The tone is adventurous, action-led, and a bit broader in scope than Dark Wen's gloomier police horror.

If you want supernatural action with a younger lead, quick escalation, and a secret-agency backdrop, this series is a solid entry point. It has demons, power struggles, and a heroine who has to work out who she is while the world tries to use her. Start with Scarlett O'Meara: Beastmaster, because it does the heavy lifting of opening the agency's world and Scarlett's part in it at the same time.
