House at the end

Four teens find a mysterious house that promises to fulfill their deepest, darkest desires and grant them great power. But how far will they go in their quest for this power? Will they turn from the darkness in time, or succumb to it like others before them? Or perhaps, the "house" has its OWN agenda.Note: Codes are for entire story, and I'm introducing some recurring characters for this universe. Oh, the youngest character is 13; don't read if that disturbs you.
