Moonbound by Sylvia Frost is about Artemis Williams. Her parent were killed by werebeasts while she hid. She's hidden for years and now is buying a gun. I gave it four stars.
She describes her friendship with Lawrence: "We may not tell each other everything, but the things we do share, we share completely. Our friendship is made of these brief moments, perfect islands of intimacy in vast oceans of secrets."
I look forward to reading the next book in this series, Huntbound.
