The three books—Print in the Snow, Over the Hills of Green and The Book of Fairfax—are a part of the same world. Our world. Or a least our world the way I see it.

The main story takes place in the novel Over the Hills of Green as a modern woman, Anna Reilly, struggles to reconcile her perfectly scientific, pragmatic worldview with her own brush with the unexplained that took place in Print in the Snow, when she was a teenager. The person who helps her do that (by turning her world upside down) is one John Doe, whose story as a 7th Century Anglo-Saxon warrior is told in The Book of Fairfax.
