Bloodlines {Book One: The Last Kill}

The Northern Savages, aka Wolves, have only one thing in mind: Kill whoever made the mysterious crime of killing their leader's pregnant mate. One of the culprits would be the Southern Savages, aka Foxes. When war breaks out between the two, along with their flying allies, it is at the darkest hour when they find out that it was neither the Foxes or any of the birds, but a new, blood thirsty group of antagonists. Past enemies will unite to fight the one thing that would destroy them all... in one, measly battle. But what drew them to kill the Northerner's mate?
