There is a new murder, and this time, it calls for a field trip. Cassie and the team are taken to Las
Vegas for the investigation. Someone has been killing people in casinos. The person has also been tattooing a series of numbers on the victim's wrists. While Cassie doesn't want to think about it, Sloane, her teammate, has been acting awfully suspicious lately.
All victims have a series of numbers tattooed on their wrist, and they're going to need Sloane's mathematical gifts to find out what they mean. That is if Sloane is on their side.
I liked that this book a had a lot of mystery in it, but not so much that it made it confusing.
There really isn't anything that I can think of that I didn't like about this book.
I give this book 5 out of 5 stars.
