I'm looking for the title of a book-series - I'm pretty sure it was a trilogy when I ran into it, but books may have been added. It's possible I may mix in details from other books/series I've read, but most should be correct.
I think the main-character is a teenage girl/young woman. She becomes the leader/alpha of a pack of were-animals/shifters, even though she herself is not (a were). She herself has grown up inside a pack of were-animals/shifters - unsure if she's adopted or if all weres in the pack had be "infected" in some way. I think there were also humans in the pack she grew up in. I think they're werewolves.
I think the pack she leads is a pack of teenagers, outcasts and others who didn't fit-in with the main pride. She has been trained to fight, and must face a challenger - I think an ex-boyfriend, brother or someone she rescued. The fight - as all fights for leaderships - is done in human form.
I think someone is left unconscious or dead on her doorstep. She plans to become a were, but has to delay it. I think it's her father (the alpha of the main-pack?) or her boyfriend that was supposed to turn her.
I'm pretty sure this exists as audio-books too.
Does this sounds familiar to anybody? Does anybody remember the author, the series and the title of the first book?
