[quote=""annis""]I don't think Kathleen Herbert's trilogy has an official series title - I have seen it described as both the
Northumbria Trilogy and the
Cumbria Trilogy - I guess you can take your pick

Trifolium Books are thinking of calling it the 'Kingdoms of the North Trilogy' when they republish all three books later this year (blog post about the various names here
http://trifoliumbooks.blogspot.com/2011 ... north.html if interested). I like the new label because it includes the Lothian settings in
Bride of the Spear and the Pennine/Peak District settings in
Ghost in the Sunlight as well as Cumbria and Northumbria. I tend to think of the three books as one stand-alone (
Bride of the Spear) and one pair (
Queen of the Lightning, Ghost in the Sunlight), because as you say, there's a jump of a generation or two between
Bride of the Spear and
Queen of the Lightning. (One of the things that attracted me to Eadwine's story in
Paths of Exile is that it falls neatly into this gap in Kathleen Herbert's novels, so I felt that his story hadn't already been told). As Annis says,
Ghost in the Sunlight follows on from
Queen of the Lightning more or less directly, telling the story of the next generation. I'm glad you're enjoying these! They are among my favourites.
