A Highlander's Second Chance

Love comes around a second time...
Clyde McMannis is not exactly happy. Who would be with his bairns and the love of his life gone? But he manages. He keeps his pain at bay with the ones he's become close to. All of that changes when a familiar face from his long-forgotten past finds him and makes him an offer.
Ailsa Dunne lost her true love and husband to war. She feels it fitting to fulfil his purpose and serve Scotland. When called to serve training young women to be assassins and spies, she answers the call. If only she could teach them everything. Alas, she cannot, so she must rely on the giant brute sent to help her. A man whose purposes seem contrary to her own.
Can Clyde save his niece from danger and at the same time keep the shrewish but beautiful Ailsa from killing him?
