Stranger at the Door — Sara Mackenzie

Previously published as Knight of Secrets under the penname Evie North. 1200 AD. Alone in her brother's fortified manor house in the icy north of England, Edwina finds herself under serge from Scots raiders. The stranger who takes shelter with her is young and handsome, and very different from the old man Edwina is set to marry. But is the stranger really everything he says he is, and do his promises mean anything? As Edwina falls deeper under his spell during the long night, dawn will bring her the answers.
