Besieged (The Scottish Falconers #1)
Diane Wylie

Catriona Dunn is the baker's daughter, just one of many people who come and go in the castle. When the dashing figure of the falconer and his majestic bird catch her eye, she is intrigued. A chance encounter brings them together one night, changing their lives forever.
United by a cause, the falconers of Dunnottar must fight to survive an invasion of their home and save the ancient regalia of the Scottish kings from the hands of their enemy.
