Second Son by Pamela Taylor

Second son is the first of the Second Son Chronicles and follows a young noble as he grows from adolescence to adulthood in a medieval setting. Captured during the chaos of battle, young Alfred is taken away from his home and family for ransom. While in captivity, he dwells on how he ended in this situation, trying to understand who and why he has been kidnapped.
This is a well researched and enjoyable read. To watch a boy
to be a man through the eyes of the author is quite interesting, as is the
difference in similar brothers with the same opportunities. I will definitely
be watching for further installments to this series.
