Memento Mori Books in Order

Memento Mori is one of C.N. Crawford's earlier fantasy series, and it has a noticeably different flavor from the later romantasy books. It leans younger, darker, and more strongly into New England history, witchcraft, and the eerie feeling that the past is still alive enough to hurt people.

The main story begins with Tobias Corvin, a teenage sorcerer from another world who stumbles into Boston half frozen and desperate. He is trying to save his home, but once he lands in our world he has to hide inside a boarding-school setting where normal rules never stay normal for long. There he meets Fiona, who becomes drawn into the dangerous truth behind his magic and the world he came from.

From there, the series opens outward.

One of the strongest things about Memento Mori is its setting. Boston is not just a background city. The books tie modern life to colonial violence, witch-trial history, old families, and secrets that feel buried only until the plot starts digging. There is also the shadow of Maremount, the other realm connected to Tobias's story, which gives the series a portal-fantasy layer without losing its urban edge.

The tone is darker and more overtly eerie than in many of Crawford's later series. Ghostly armies, cults, cruel school politics, and old-world magic all sit close together. The books are interested in horror touches as much as romance. That does not mean they lose emotional warmth, but it does mean the danger often feels more unsettling than glamorous.

Fiona and Tobias anchor the larger trilogy, while entries like The Abysmal Sea expand the edges of the world. Across the books, young characters keep finding themselves trapped between inherited systems of power and the need to break them. Adults are rarely fully trustworthy. Institutions are worse. Magic is valuable, but it almost always comes with a cost.

Another thing that stands out is the mix of historical texture and supernatural chaos. These books like old graveyards, old grudges, and the idea that a city can remember what was done there. That makes Memento Mori a good fit for readers who enjoy dark YA fantasy with a sense of place rather than pure quest fantasy.

If you are coming to Crawford mainly for the later fae romances, this series will feel like the roots of a lot of those interests, just filtered through younger characters and a spookier New England lens. It is a story about witches, parallel worlds, and the fact that some histories do not stay buried, no matter how badly people want them to.
