This realistic story of America’s war in Vietnam uses the alternating viewpoints of an army dog named Cracker and her 17-year-old handler, Rick Hanski. From their training at a base in the U.S. to their stalking the enemy, the tale explores the close bond of the scout-dog team, relating how it detects booby traps and mines, finds the enemy, rescues POWs, and returns home to a heroes’ welcome.
