Isabel Marshall

Formerly the son of William Marshall, 2nd Earl of Pembroke, Robin Marshall accompanied his father to the war in Ireland, but lost everything when his father angered the Bishop of Ferns, Ailbe Ua Maíl Mhuaidh, who laid a curse on the family, to ensure that the Earl would have no male heirs.

Cursed with the Curse of Macha, which afflicted the Men of Ulster many centuries before, Robin Marshall now has the body of a maiden & must pretend to be his own sister, Isabel.
