Many of us animal-lovers fear that shelters filled with plaintively barking homeless dogs would be an impossibly depressing place to volunteer. But in Rescuing Penny Jane, author/journalist Amy Sutherland shares how working with countless scared and "humanless" dogs actually leaves her "surprisingly, exhilarated." Her positive experience is due primarily to the "ample, infectious joy" of the lovable pups, but also to the inspiring dedication of the shelter experts and activists who strive to find a home for every dog. Sutherland charmingly introduces many of the remarkable dogs she has fallen in love with over the years (trust me, you'll be smitten, too!) and leads the reader through the interesting history and philosophies of rescue shelters around the country. Dog-lovers will find this unique memoir/portrait of the rescue world both moving and uplifting. (CH)
