Query: Review for Tithe

The book Tithe is a great but also complex book. It can be quite hard to understand at times but in the end you can pretty much piece it together. It is a story that makes you wonder, "What's going to happen next?" This fantasy story also has some romance and action. It's two main character's names are "Kaye" and "Roiben" and together they go through great adventure and threat.The description in this book makes you feel as though you are actually in the book, looking at the characters and the environment. It is about two courts of fantasy creatures (the Seelie and the Unseelie courts). The Unseelie court is the controlling court, and to remain in control they have to "tithe," or sacrifice, a willing mortal. It is interesting how the author came up with this idea for the book. Once I picked up this book, I could barely put it down. This is a great book if you enjoy a great quantity of fantasy and fiction creatures and places.
