long story short, charlotte's father left her and her mother like they were trash when he found a shiny new play thing. i'd imagine he's gone through a billion women at this point, but he and his current wife have a child and that child got the life charlotte was supposed to have before hers imploded. charlotte is a jealous, petty little psychopath about it and is actually planning to kill both her father and stepmother. i was hoping her half sibling would be a hero of sorts who always tries to extend a hand and offer her a better life and show her that stealing, lying, and cheating will get her nowhere and she deserves so much more, blah blah blah. i'd be open to changing all sorts of details, but that was the basic idea in my head!
