To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Interesting fun characters, fairly easy to keep track of who is who, without constantly needing to look back. Story gets a little out of the realm of believable from time to time but still fun to read.
Once you get past the subplot of the story's point person busily charting everyone's sign with stars and planets -- particularly in the first quarter of the book -- things get interesting. Once we get the body and down to business, there's a rather satisfying mystery with several suspects and corpses getting their galactical dues. And the by the twist at the end, our heroine is counting her lucky stars.
