The Sea Stranger, The Fire Brother and The Earth Father were written by Kevin Crossley- Holland. http://www.kevincrossley-holland.com/ The trilogy describes the life of a Saxon boy, Wulf, and how he is converted to Christianity around 653AD when the monk Cedd comes to East Anglia and builds St Peter's Chapel in Bradwell-on-Sea. When I did the illustrations for these three books I didn't know East Anglia, but later when I married, my husband and I bought a derelict farmhouse in Suffolk which we restored, so I came to know and love that part of England very well.
In the last book, The Earth Father, Wulf journeys to Northumbria to visit Cedd who is dying of the plague. The following illustrations show the change of landscape from the flat Essex coast to the stony moors of the North.
