The Loop — Nicholas Evans

A pack of wolves makes a sudden savage return to the Rocky Mountain ranching town of Hope, Montana, where a century earlier they were slaughtered by the thousands. Biologist Helen Ross has come to Hope from the East, fleeing a life in shambles, determined to save the wolves from those who seek to destroy them. But an ancient hatred awaits her in Hope, a hatred that will tear a family and ultimately the community apart. And soon Helen is at the center of the storm, by loving the wrong man, by defying the wrong man... by daring to lead a town out of the violent darkness of its past...
