The Grace Factor
Arabella Grace lives in a world in which werewolves are seen as fables, and humans go about there lives without the knowledge that danger lives among them.
Arabella is special, and not only because she is the daughter of Roman Grace, Alpha of all of North America. She is special, because she is the only known living female werewolf.
The werewolf gene skips any baby girls born to a wolf father, and women aren't physically able to survive the change if bitten.
The daughter of Alpha Roman is a miracle child- but this only puts his beloved child in danger. Rival packs believe that they can use Arabella to breed with and create strong werewolves, with the hope of extinguishing the problem genes that prevent female wolves from being created.
