Fire Across the March

[Description from inside the dust jacket of the book, since there is no description on goodreads]

The Normans were the conquerors, the oppressors, the new lords of England. Tales of their tyranny, their greed for land, had traveled before them, even into the remote corners of the Welsh Marches, and men feared and hated them.

Nothing could have persuaded Elfreda, daughter of a Saxon thane, into marriage with one of the invaders, except the hope that the union would save her father's people from further bloodshed.

But the Saxons would not accept their Norman overlords and soon rebellion was flaring along the length of the March.
