All Types of Monsters

Ever since Peggy Dean died, her life has gotten a hell of a lot more difficult. The fact that she should be six feet under drags on her, keeping her in bed. Once so confident and caring, Peggy begins to question her entire life. Barely held on to earth by her sister and her best friend, Peggy begins to research what she thinks are tethering her to her dark bedroom: demons. By doing so, she hopes to expel her inner beasts. When she stumbles across something that probably no mortal should have seen, strange things start happening to her friends and family. And then scary things start happening around the world. Soon, it's not just her inner demons Peggy is trying to take down.
Armed with nothing but a book on demonology, her sister and friends, and an old, rusty Crucifix, Peggy tries to take on the creatures from hell herself.
