The Shifters: Book Two 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.
