From publisher blurb:
Rangers are a dynamic class, competent and resourceful in various situations and environments. This supplement adds to the class's inherent versatility and presents options that instead make a ranger more specialized.
Rangers Renewed contains several new combat styles, options for favored terrain bonuses, and ways to make rangers deadlier against their favored enemies. Also included are over a dozen new feats for ranger PCs and animal companions, and expanded combat styles going to 16th level!
