   Summary

   14 yo Gabriel has lived his whole life in fear of his spoilt brat older sister Florence. She's always been meaner, stronger, taller, and just plain nastier than he could ever hope to be.

   Thanks to a chance encounter with a cursed item shop on a rainy halloween day, he ends up in a position to finally teach her a lesson for good: A complete set of rubber magical human domestication tools.

   Will Gabriel let the power get to his head? (Most certainly) Will Florence learn to love her new position of rubber bound human pet? (Might be a tough sell.) Will the two of them ever find common ground? (Remains to be seen.)
