for cassie her families horse riding school has been her life and they have been showing her how to ride horses since she was little now 9 years old she went for a ride almost every day after school. the bussiness was quite profitable and they were expanding the stables so her parents decided to give cassie her own horse with one of the new stables so they secretly got cassies best friend maria over one afternoon without her knowing and took her to the new stable to show her maria loved horses as well on arrival they gave her an apple as maria ate it something felt weird in her within a minute maria was no more she was a horse with no recollection of being human and her mind suddenly filed with horse thoughts and being loyal to cassie. when cassie found out she was getting her own horse she smiled not realising it was her best friend until she heard maria was missing and figured out what was happening but it all ends well.
