Cairo Sloane Adventure Books in Order

The Cairo Sloane books branch out from Rob Jones's Joe Hawke world, but they do not feel like a side project. Scarlet Cairo Sloane is already the sort of character who can carry her own story, and Plagues of the Seven Angels makes that clear very quickly. She is tough, smart under pressure, and already used to operating in the kind of danger that makes most people turn around and head home.

This is a spinoff with teeth.

The central setup is pure Jones. Cairo's brother is snatched off the streets of Berlin, and the kidnapping sends her into a frantic hunt for an old Nazi map and the final resting place of the Staff of Moses. That would be enough for most thrillers, but the story keeps widening. What begins as a family crisis grows into a larger race for a far more notorious treasure and, behind that, a buried secret with the power to threaten millions of lives.

The tone will feel familiar if you already know Joe Hawke. There are clues to decode, enemies who never stop pushing, and a route that runs across multiple countries and keeps the pressure turned high. From English country houses to Washington, from Venice to Kiev, the book moves fast and likes to keep its heroine off balance. Cairo is not wandering through museums with a notebook. She is chasing answers while trying to stay alive and keep someone she loves from disappearing for good.

What makes this branch interesting is the change in center of gravity. Joe Hawke novels often work as team adventures with lots of banter and a broad cast. Cairo's story still has allies and a mission bigger than one person, but the emotional pull is more personal. The danger lands closer to home, and that gives the book a sharper edge. Her competence is never in doubt, but the stakes are not abstract. She is fighting for family as much as for the wider world.

At the moment, this is a compact corner of the Rob Jones universe, built around one published adventure. That actually makes it easy to try. If you want the same mix of relics, conspiracies, and hard-running action found in the Joe Hawke books, but with a different lead and a more personal engine, Cairo Sloane is a good place to jump in.
