Highlight for me is the library of 3,000 plus words with a clear pronunciation.
Maybe it says in the description, but I "assumed" it was going to read the story, which it doesnt. What it does is gives you a set of words to learn for each chapter before reading it. The story starts out with ridiculously basic grammar, and picks it up a bit as it goes. Worth the loot that I shelled out.
