Bonded - Bonded, Billionaire Shapeshifters, #1

Roman Davenport thought he was the only shifter in existence-a freak. He first shifted to a panther when he was twenty years old. Now, in his forties, he and his panther are so lonely. Then he rescued Gage Stryker, an eagle that had been shot from the sky with an arrow through his wing. Like Roman, Gage thought he was the only shifter. Roman and Gage were so happy to have found each other. They spent the next fifty years searching for their kind-and searching for mates.
Relationships with women were short-most only wanted the limelight of the city's two most eligible bachelors. Then Ari Davis crossed their path. The woman was seventy but looked not quite fifty, with thick white hair to her waist. The attraction was a powerful pull for all three of them. Ari was so confused by the strong attraction to the men-that were barely older than her two sons-that she fled to Mexico for a week to try to get her head straight.
When she returned home, they were there-waiting for her. Nothing would ever be the same for any of them again. They formed a bond that could never be broken. Adult content.
