Do you remeber the old Choose Your Own Adventure books? Simon & Schuster Children's Publishing have decided to revive the concept with book apps. They've released one title so far, Return to the Cave of Time, with more titles coming in the fall.
It's unfortunate that they took so long to release this. It doesn't have to be done as an app and could quite easily have been done in Mobipocket/Kindle. I know that I could have designed it.
As someone who read CYOA books back in the 1980's I couldn't resist.I immediately downloaded and read it. I'm kinda glad that this is an app. They've taken advantage of the possibilities of a book app and integrated some interesting backgrounds and sound into the story.
It's worth getting. You can find it in iTunes for $3.99.
