Heat of the moment

Ruby is an everyday horse rider/lover. Sam was her little paint horse her championship jumper, racer and dressage. What ever Ruby put Sam into they always won. Ruby had Sam since he was a little foal and had fallen in love with him the day he was born. She trained him up and in no time he was racing around with her on his back. On Ruby's 21st birthday the world she knew turned to dust as war broke out. The pain of loosing her family was too much and slowly drove her insane. Well that what she thinks any way. She woke up one day not quite herself. Trapped in a horses body only with Sam as her guid I wonder what will happen. (;
