Green Men Books in Order

The Green Men books are KJ Charles's occult England stories, where the supernatural feels old, invasive, and only partly understandable. This is not decorative fantasy. It is hauntings, folklore, rituals, things in the dark, and people who are trying to keep a grip on ordinary life while the world keeps proving it is not ordinary at all. The series links different eras and protagonists, but the shared mood is unmistakable.

At one end of the setting is The Secret Casebook of Simon Feximal, with ghost-hunter Simon and writer Robert Caldwell moving through investigations from the 1890s into the early 20th century. At the other is Spectred Isle, set after the First World War, where disgraced archaeologist Saul Lazenby and occultist Randolph Glyde are pulled into a threat that feels both personal and much larger than they first understand. The books are connected by world and character ties, but they are not doing the same job. One leans into occult-detective casebook storytelling. The other is more like a bruised, eerie postwar romance with a mystery at its center.

Magic here is uncanny, not decorative.

That difference is part of the appeal. The setting is broad enough to hold ghostly investigations, family obligations, old magical bloodlines, and the psychological damage left by war. Charles writes both books with a strong sense that the supernatural does not exist in a vacuum. It attaches itself to class, secrecy, shame, grief, and the practical business of getting through the day. Simon and Robert's England is one of case files, journalists, and occult threats hiding in plain sight. Saul and Randolph's is a shaken 1920s world where trauma and haunting are hard to separate.

The romance in these books is tender, but it is never light. Trust has to be earned in cramped emotional conditions. People hide things for reasons that make sense, even when those reasons are terrible for a relationship. That gives the books a melancholy undertow that is different from the brighter snap of the Magpie novels. Even the wit is drier here.

If you want Charles at her creepiest and most atmospheric, this is the corner of the bibliography to try. The broader series feels unfinished in the sense that the world clearly has more room in it, but the individual books still satisfy on their own terms. Come here for occult trouble, damaged men, and the sense that England has old roots and not all of them should be dug up.
