Birthright - Anna Markland

Adam de Montbryce must come to terms with devastating losses that may cost him his birthright. Dare he trust the woman he loves with his terrible secret? His half brother, Denis de Sancerre, is determined to stand by his beleaguered brother. Can Denis find love despite his dwarfed stature? He has never risked his heart before.
Set in the 12th century against the backdrop of the magnificent Arundel Castle and the eerie ancient monoliths of Carnac in Brittany, Birthright is the tale of The Giant and the Dwarf, brothers haunted by secrets. They struggle to come to terms with physical impairments in a medieval world where survival of the fittest is a stark reality.
