Dawn by Sherry Foster

She won’t be a pawn.
She won’t play their game.
Dawn must find a way to break free of her captivity. If some people have to die in the process, well that’s just collateral damage. She is determined to find a way out of her prison so she can search for her friends. She may not know where she is, or how she will escape, or even where she will go, but she is determined to break free.
When she makes her plans she doesn’t count on having inside help.
Now they have to find a way to outsmart and outthink the ones holding Dawn captive. Men who will stop at nothing to collect all the female shifters they can get their hands on.
In a race against time who will win? The captors? Dawn and her helper? Or will Marcus’ pack make it to the prison before everything goes to hell?
