Cassie Parker was always full of life. One night changed everything, she became full of death. Murdered by a person she can’t remember and for reasons she doesn’t know, she uses her dying breath to pray for a chance to catch the person who took her life. She never thought her prayers would be answered. She's flung into a world so different from her own. Limbo. All she wants is to find her killer and move on but nothing runs smoothly for Cassie in her quest to reach heaven. Her memory of the day of her death is as clear as mud. The angel-in-training who's supposed to help does nothing but flirt with her. And she finds herself fading away, slowly forgotten. Her parents and friends all carry on with their lives without her and Cassie can do nothing but watch.
