Eochaidh: Legend Of The Horsemen Books in Order

The Eochaidh books sit in the fantasy corner of Terri Reid's work, and they feel very different from her small-town ghost mysteries. Here Reid turns toward Arthurian legend, Irish setting, ancient curses, and a much older kind of magic. The central idea is a strong one: long ago, young knights connected to Camelot were trapped by Morganna and transformed into horses so they could survive a terrible spell. They have lived on for centuries, waiting for the curse to be broken.

It is a wonderfully storybook premise.

The human side of that burden falls to the Herdin family, whose line is charged with helping the cursed horsemen and, if possible, setting them free. In Eochaidh, Reid places that struggle in eighteenth-century Ireland and uses Meaghan Herdin and her family to carry the emotional weight of the tale. That choice matters, because it keeps the story from floating away into pure mythology. The curse is ancient, but the people trying to break it are very much alive, frightened, loyal, and imperfect.

Expect romance, adventure, danger, and a good amount of fae-inflected atmosphere. The books are interested in courage and devotion, but also in what a family owes to a promise that began long before any of them were born. Reid does a nice job of making the magical setup feel personal. The horses are not just symbols. They are trapped men with histories, and that gives the fantasy a mournful edge underneath all the action.

If you come to Reid mainly through Mary O'Reilly, this series can feel like a side door into a different part of her imagination. But the same interests are still there, family, unfinished business, sacrifice, and the stubborn persistence of the past. This is the series to pick up if you want the most openly mythic version of her storytelling.
