Feral Moon - Dirigo Pack Series, #3

A wolf lost to madness. A princess destined for another. A forbidden love that might save them all. Maddox knows he's losing his mind. He can feel his grip on reality slipping, just as it did for his father. The reason is simple. He's waited too long to find his mate. With Moon Madness creeping in, he fears time has run out.  Until a kidnapped princess is dropped at his feet.  Kayleigh is the daughter of his greatest rival.
Yet, the instant their eyes meet he feels the rush of the mate bond. Maddox aches to claim her as his own, but failure to return Kayleigh to her pack could start a bloody war.  Honor demands her freedom. Love requires their surrender.
