** spoiler alert ** I like this book, its really interesting,
i think that the stranger used to own Winnie Fosters house and saw the Tucks drink the water that makes them live forever! And he know about the secret and maybe the stranger dinks the water too. I also think that after the stranger told Winnie's parents he knew where she was he is going to capture the Tucks. But i also say that when Winnie is 17 Jesse will ask her to drink the water from the spring but she doesn't because Angus Tuck told her how horrible it is to live forever and how he would do anything to reverse it. I cant wait to read more!! The details are great too! I think that the stranger will capture Winnie and hold her for ransom so he will get even more out of the Fosters, besides their woods.
