So far in the Alpha and Omega series, Hunting Ground is my favourite story. Charles and Anna are both werewolves, but where Charles is an old werewolf, Anna is young, inexperienced and emerging from some serious trauma. The thing is, their wolf natures don't care about their differences. They're mated.
In the first two Alpha and Omega stories, no matter how much Briggs softened the reality, Charles and Anna's coming together had a forced element. They were ruled by their werewolf natures. But in Hunting Ground Charles and Anna are exploring their relationship, Anna is growing in strength and it feels like a romance to me, one backed by a solid, suspenseful story, set within a well-realised urban fantasy universe.
