Becoming is the first prequel to Cry Sanctuary (the story of Keith and Abigail). Set forty years before in fact.
In this, Keith is only seven years old. But the story itself centers on Samantha, a twent-six year old woman who's been turned into a werewolf. Living with Keith's family after surviving the hells of her former alpha, she is introduced to Gavin, the alpha of her new pack.
Gavin is a sweetheart. To Keith. To Samantha. To everyone. He even survives meeting her rich papa. The story only goes so far.. basically until Sam lets Gavin know that she's claimed him. Even though she's not ready to actually seal the deal, that doesn't make him any less hers.
