The Nuclear Family (A St Jimmy Story/Fanfiction)

Jimmy was just a sixteen year old only child living in Jingle Town. He thought his life wouldn't change, until he found out about his long lost dad's death. Curious to know more, he decided to go to the funeral to find out more about him and found out something a bit unexpected, in fact ELEVEN unexpected people-his half siblings.
None of them knew about each other or knew their dad and most were curious to know each other.
Out of all the eleven Jimmy found one who was understanding and kind, but is he willing to open up to her and protect her from the dangerous world? Would he be willing to fight siblings, parents and teachers to keep her around?
