There's a new rider at Pine Hollow Stables. Her name is Tiffani, with an "i." Carole Hanson and Lisa Atwood think she's a good rider, but Stevie Lake can't get over her riding gear -- pink and covered in lace and frills. Suddenly Stevie's in competition with Tiffani, determined to win at all costs -- even if it means learning to jump fences riding sidesaddle. Stevie's friends are convinced that she has lost her mind. But Stevie's determined to "out-girl" everyone. She's even bought a fluffy, pink sweater!
