Life After Theft - Aprilynne Pike

If you start reading this book and expect a doomed love story between a ghost and a human. Don't. There is a love story but it's between two humans. This book is more concentrated on sending a message and how our choices effect us, and people around us. 
This might be one of my favorite books because it was funny and serious in places where those emotions needed to be. Also the plot and characters were original and fresh making me want to read this as soon as possible.
