for jessica it had been a lonely year her brother scott who went missing the previous christmas in a way that her parents didn’t want to explain other than the fact that a nearby horse stable got a young male mare on christmas which everytime jessica goes there looks at her in a weird way. on christmas eve as she went to sleep her parents snuck two pills into her water one made her sleepy the second did something to her they than put her while she slept into a horse trailer and as it hit midnight her body changed into a young female horse. christmas morning she woke up to a familar voice her brothers but all she could see was a horse he explained what happened that in the family they have to spend time as a horse as their mum was a horse but couldn’t reproduce so made a deal with a human to help raise the kids that she couldn’t have but in exchange would have them turn into them on their 5th christmas this stunned her but than a bigger horse explained everything and than did something to remove their human memories they were horses.
