Swap Over — Margaret Pearce

Maddy had a best friend who had everything, wealthy doting parents, attended an exclusive school, owned her own horse for gymkhanas, and she was well liked and popular as well. Maddy lived in an ordinary over crowded little house, with two unpleasant sisters who crowded her bedroom and her life. Her parents didn't have enough money for anything extra and didn't seem to care that she was missing out on all the good things in life. She attended an ordinary school with her sisters.

Maddy's wish that she could swap into Jennifer's life is granted. So she has Jennifer's privileged life, and Jennifer has her boring poverty struck life. So why is she still unhappy, and why is Jennifer still happy, well liked and popular?
