Rise of the Wolf by Curtis Jobling

Amazon.com

Drew grows up on a small farm, which I learned from Mr. Jobling was based off a fantasy version of the US.  (Previously, I had a European map in my mind!)
One evening he and his mother are attacked by a werecreature and for the first time, Drew changes and becomes a werewolf.  After running from home when his father returns and mistakenly believes he killed his mother, the first book in the series follows Drew's adventure through the kingdom as he discovers how to use his ability to transform and learns his rightful place as king of the werelords.  There are six books in the Wereworld series.  A great read!
