Island of the Mighty

Island of the Mighty retells the last branch of the Mabinogion, the story of Gwydion, Arianrhod, Llew Llaw Gyffes, Blodeuwedd and Goronwy. It begins with a retelling of stealing the pigs belonging to Lord Pryderi. Gwydion uses this to provoke war, allowing his younger brother to rape the king's footholder. This also leads to the death of Pryderi, which doesn't endear Gwydion to the reader who has also read the retellings of the other three branches -- and also to the disgracing of Arianrhod and the birth of Llew Llaw Gyffes.
