When Morgan de Wolfe, commander of Richmond Castle, is called by his liege Caius d'Avignon (Winter of Solace) into the full-fledged world of the Executioner Knights to go deep under cover, a de Wolfe becomes a Wolfe in sheep's clothing for the sake of William Marshal and his spy ring. Will a de Wolfe be the greatest Executioner Knight of all? Morgan de Wolfe, cousin to Edward de Wolfe, Earl of Wolverhampton (and father of William de Wolfe of The Wolfe), finds himself the perfect man for an Executioner Knight's job. Assuming the identity of a dead man, he makes his way to the Welsh border to infiltrate his way into a castle stolen by a Marshal enemy. His task is to use the dead man's identity to reclaim the castle. What he didn't count on was a woman who could quite possibly ruin his mission. And possibly even his life. Amarantha de la Haye's father assumed control of Mount Grace when King John betrayed the owners and confiscated the castle. Unaware of how, exactly, her father came to command the mighty castle and control its silver mine, Amarantha has lived in peace at Mount Grace, an educated and clever young woman but finds herself a pawn of her ambitious father. When a chance meeting with Morgan sees sparks fly between the two of them, she has no idea that she will be the key to Morgan's mission... and possibly her own destruction. The Wolfe fangs are sharpening. Join Morgan and Amarantha on a complex journey of lies, deceit, betrayal, and ultimately the power of love. Will Morgan obey William Marshal? Or will he obey his heart? Of Mortal Fury is part of the USA Today bestselling Execution
