What books should have a video game?

There's been plenty of times that a book I've read has enough detail and elements that could be used in a video game, whether it be an open ended RPG, plot driven RPG, action RPG, RTS, TBS, FPS, third person action, sidescrolling shooter, adventure, or anything.  What books or book series have you read and thought they would make a cool game?

It is a story about the love between a man and a woman.
