Enter is a psychological thriller - a book that takes you into the mind of a serial killer from the beginning of his madness to the best ending ever! This is the first book of a sequel. You won't want to stop listening and you will dream about the moment you can resume. A pause resister as well as a great listen. The one thing every listener says is "I want more!" April O'Brien is a great story teller, draws you in, and holds you there.
