Hunted (The Scottish Falconers #2)
Diane Wylie

Although he was raised in Scotland, Derek Sinclair is an Englishman. He makes his living as an English soldier. Ordered to attack and kill his former countrymen, he finds himself injured and the only survivor of a skirmish with Dunnottar men-at-arms. Now, he must become a Scotsman or die.
In this exciting sequel to BESIEGED, the falconers of Dunnottar continue their sacred mission to protect the ancient regalia of the Scottish kings.
