Both the books in the series made me think "wow, this sounds awesome, I'd like to go through that in a videogame." That feeling was even stronger with the second book, because exploring a strange island with strange fauna sounds great.
One point off because it wasn't as good as the first one; another point off because it was way too dragged out. Scott Brick is a good narrator, but the narration was very slow and needed a big speed boost.
