QUICK CONCEPT
Half-Sister to the Baker Boys in the Eureka Pack. Raised by her Grandparents in Mercy Cove, though her Mom is still around. While not a member of the Eureka Pack, she has been dragged into their crap over the years on account of being kin, even if the connection is not formally recognized by the Pack. Some assume she knows more about them than she does. Others think they can use her to get to them. The brothers themselves think they can call on her as needed on account of their shared DNA. She just wants to be left out of all of it.
ANYTHING ELSE
It's still a very loose idea in my head but I liked the idea of playing into the politics between the two packs. A rogue wolf who can never fully be trusted by either pack and often gets used as a pawn.
