Santa's Angels by Janet Kaderli

You have a mom who is trying to make ends meat working two jobs and raising a daughter by herself.  You have an athlete who has let it go to his head and is now paying for the troubles he has caused.  On top of that it is Christmas.  These three things come together in a very neat and simple story of stepping outside of yourself, being gracious and experiencing the true meaning of Christmas that we should experience all year long.
