The bone thief

"Edward, son of Alfred the Great, has inherited the Kingdom of Wessex and achieved a precarious set of alliances through marriage and military conquest. But the alliance is uneasy and the kingdom of Mercia has more reason than most to fear the might of Wessex. Their Lord is elderly and perhaps mortally sick, and his wife fears that she does not have the power to withstand hostile takeover. She also knows too well what her neighbour is capable of - after all, King Edward is her brother."--Publisher description.
