American Girl Corinne Tan

13 year old Corinne Tan is secretly unhappy with herself because she has no obvious skill that makes her stand out; she feels that she is not pretty nor witty nor bright, and her splintered and reformed family dotes on her sister Gwynn, a gifted skater. When Corinne comes across a dog on the ski slopes who apparently has no chance of making the grade as an Avalanche Rescue dog, Corinne grits her teeth and digs in, determined to help this dog learn its mandated skills.
