At twenty-four years old, all Jack Hesley knows with certainty is he's head over heels in love. But his life (and love) veers from center when his brother's car careens across an icy Wisconsin interstate and into a stand of pine. Stunned by loss, Jack retreats into isolation - a depression so stubborn the only thing forceful enough to cross its threshold arrives in the shape of wild bears. He dreams them. He becomes obsessed by them. And he alters the trajectory of his path forward, risking limb and love, to follow real bears, grizzlies, into the thick woods of western Montana to untangle their impossible message - to become one of them.
