Reunion with Her Alpha (Paranormal Werewolf Romance)

Growing up, Marty and Mila were inseparable, so much so that people called them M&M. But one day, Marty moved away without word or reason and Mila thought that he had left her behind. But what Mila doesn't know is that Marty is a werewolf who was forced to leave to protect those around him. What she especially doesn't know is that he was her wolf, and she was his mate. When Marty suddenly walks back into her life, Mila--now engaged--isn't quite sure what to think.
Can she find it in her heart to accept the lost love he promises to return or will her responsibilities to her new life give her no choice but to deny him?
