if thats the case then what is the point of them even being here? If they are to prevent their future from ending up as it is now, then what is the point of them going back with their memories erased of how things turn up? They will have come here and gone back with absolutely nothing accomplished. Which means the weeks or months by the time that happens spent here will have been a complete waste of time for them. No character development. No gain in skill and experience. No knowledge of whats to come to help prevent it from occuring, etc... Like I said earlier, the premise behind this book is stupid. Its an enjoyable read of course, but I dont see the point of any of this.
