text: what is the book in the lake house that kate(bullock)'s dad wrote? is it called persuasion? i can't find it. kate loved that book and it was the one that she left behind when she was leaving. i think it's called persuasion or something but i can't find it. does someone know the book? is it a real book? i need the real title and author. can someone please help me? "persuasion" is a real book and it's written by jane austin (as shown by the cover in the movie).  the plot is the same as sandra bullock's character describes.  as for locating it, you can find it at most book stores and online (it's a classic novel and available everywhere).
