Bound By Fate by Skyler Snow

Books and his nieces. Those are the two most important things in Nikhil’s life. And it should be enough. Until he realizes how lonely he is and how anti-social he’s become. When he runs into the energetic and feisty Evander his world gets turned upside down.
Evander is tired of only being wanted for one thing. Bunnies aren’t known for lifelong mates, but when Evander runs into Nikhil he finds himself wanting the alpha. Forever. Even if the wolf constantly puts his foot in his mouth.
Can they open up and learn to accept the gift that fate is offering?
