iPoe 2 (not a game) -> Free for a day
If you've ever used the first iPoe, you already know it's a superb "enhanced book" app. It features some of the best illustrations I've seen and great extras. It looks like it downloads the data when you use it; that's why the filesize is so small. If you have even a passing interest in the works of Edgar Allan Poe, don't pass this up!
