In need of a home!

It's with a heavy heart I'm in need of a new home for my Gracie. She will be 4 in July. Got her as a kitten and when she turned adult she changed... she hates my kids and is scared of everything! We have tried to make her come around and nothing works. She must be in a home with no kids or other pets! She is spayed and never scratched on anything but her post. She is a very well behaved and beautiful cat, but I can't have her hissing at my kids every day and being so mean to them. I have food, litter, toys and her bed that can go with her.
