Love is a Whirlwind (The Shifter Chronicles 2)

As a bull shifter, Ryan has no idea what it is to be human. When he's purchased and brought to the home of Caleb O'Connell, he's determined to show the young man who's boss. However, Caleb won't cooperate, and instead of fearing Ryan, Caleb takes a liking to the new bull he soon dubs Whirlwind.
Caleb adores the feisty Whirlwind, convinced the bovine will be the best bucking bull in the Professional Bull Riding Circuit. Then one night his entire life changes when he learns Whirlwind's secret—the secret of shapeshifters.
Ryan and Caleb become the best of friends, and Caleb attempts to teach Ryan, as best he can, how to be a human. Their time together leads to deeper feelings... and eventually they decide to give a relationship a chance. Unfortunately, Ryan is kidnapped, and Caleb has to call in the Agency—an organization that protects shifters—or their new life together will end before it ever starts.
