Do you think this would be a good idea for a book?

Weird. No I think that all 5 friends go camping and then while everyone asleep one of the friends pull out a knife it should be the boyfriend Tom and he kills everyone but his girlfriend and then they go inside the tent and do stuff and then she gets pregnant and they kill her and his parents so they don't find out and soon they kill everyone and turn them into wax and put them in a wax house! haha i'm just kinda copying House of wax
