Sir Nicholas had the task of rebuilding Ravenmoor Castle on the Scottish border and gaining the trust of the locals after the last Castellan terrorized the people. On the quest of finding out who was plundering the Scottish border, he met up with a lad named Thomas. Thomas was a likable lad or is he. This was a well-balanced book with mystery and romance. I really feel in love with Sir Nicholas and his Lady love Elizabet.
I really hate endings. Especially when the books have you bond so quickly with the characters. The good thing is the second installment was not hard to follow. If you never read any of Diana Cosby books, make An Oath Taken be your first book, to begin with.
