Ryan and Caleb became the best of friends while Caleb taught Ryan as best he could about being human. Born a bull shifter named Whirlwind, Ryan was taken in by Caleb's mother, who wanted to protect him—just as Caleb did. Their time together leads to deeper feelings... and now they've decided 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.
