When a series of grisly deaths in Alaska suggests werewolves may be involved, Jeremy sends Clay and Elena to check things out and take care of the mutts responsible for the killings. While looking up some old pack mates, Clay and Elena stumble on a crime that shakes them to their core. The mutts are killing pack members and obviously have a plan to take over or replace the existing pack.

Tracking down the mutts is easy enough; they're not big on finesse. But what they lack in brains, they more than make up for in single-minded determination to eliminate all obstacles, starting with Clay and Elena. The Land of the Midnight Sun is cruel and unforgiving if you're not up to the challenge.

On their own turf, no one is better than the Beta and his mate, but in the frozen forests, there are wild magics at work that keep the pair off balance and uneasy. And a beast that's as much myth as animal roams the land, guarding his boundaries against interlopers. He doesn't much care for the sudden influx of werewolves in his territory; they upset the balance of his world and threaten to draw attention to it. He wants them gone; quickly, quietly and as permanently as necessary.

FROSTBITTEN is one of the best books I've read all summer. Armstrong keeps her world fresh with every story, not an easy thing to do. There are few series that don't degenerate after four or five books in. This one keeps going, fresh and strong. The Women of the Otherworld series keeps moving and changing. Apparently, the word stasis is not part of this talented author's vocabulary.
