This book was both science fiction and a mystery that needed to be solved. I liked that I could not figure out the mystery until the author told what happened. It kept me guessing and interested all through the book. I usually figure out the ending after the second clue in most mysteries. This is probably one of the best books I have read in a long time. I wish this book was a series, I would like to read more just like this one. I have read some of the author's other books about Emily Winsnap and I really liked those too.
