More like 4.5 stars, but I didn't see where they mentioned the most important important (at least, for me): landscape orientation! To be honest, the writing tone is not much different from the first story, but the stories are great, nevertheless. There were tension and worries you'd have for the main character, and though it may be obvious, it's still surprisingly effective when the main character uses your name to speak to you.
