Wicked Wolf by Ashlee Sinn

Jack Mitchell liked his solitary life. After dealing with the destruction of his first pack and learning how to live with his new one, Jack wanted nothing more than to be left alone as much as possible. Even his annoying pack mates couldn’t force him to socialize. But when a quiet, yet strong-willed woman from the ISC takes the time to get to know him, Jack suddenly finds himself wanting more.
Lindy Taggart was tired of running. Her recent move to Colorado was supposed to give her and her twin boys the safety and security they needed to start over. With her job at the ISC, she would finally be able to support her little family and hoped they could continue living in anonymity while hiding from the boy’s father. She didn’t need any more complications in her life. Especially not an angry, secretive, and broody one.
But Lindy never expected to meet someone like Jack. Private, mysterious, and incredibly handsome, Lindy couldn’t hide her curiosity about the wolf’s past. Jack knew he had to keep some parts of his family history a secret, even if it could help the woman he hoped would be his mate. Their time is limited as Lindy struggles to conceal her boy’s powers while their father hunts them down. Jack must make a decision—reveal who he truly is or lose his one chance at happiness. And either way, it’s a choice that will change his life forever.
