Kiera Davis is going through tough times. She thinks her husband is having an affair, her teenage daughter is being rebellious, and Kiera's been having awful migraines, with bright flashes of light preluding them. She wants to think the migraines are normal, but she knows there's more beneath the surface-maybe connected to a haunting event in her past that she'd rather just forget about. Kiera's been living with a dark secret since high school, and feels the time is near for when she will be punished for it. Kiera feels like she's being haunted-by someone from her past, and by her vestigial twin whom she thinks is inside of her. Kiera ponders that her vestigial twin came to her to remind her of her past. When her friends are murdered, she has to face the truth. At each crime scene, witnesses say a woman who looked like Kiera was seen at each murder. But Kiera believes it couldn't have been her, because she was always in a different location than where the murder took place. As Kiera tries to put the pieces of this puzzle together, she tests her sanity, strength, and spirit as she tries to come to a logical decision through all of this.

Unbroken was a very interesting book. It had a lot of unconventional twists and turns in the story, and I must say that after receiving the book to review and reading the back cover, I was very skeptical about if I even wanted to read it. After you get past Unbroken's unusual oddity (the whole vestigial twin thing) and get into the mystery and suspense of "who's killing Kiera's friends?!?," it makes for an interesting, yet quirky, horror book. Sci-fi fans will love it! Unbroken's not for people who are in the mood for reading about characters with good morals. It's not that the characters are bad, but they just aren't faith-centered, so if you're looking for a book like that, this probably isn't for you. Unbroken also has a lot of harsh language in it, so this book is best suited for mature readers, around ages 15 and up.

Because of certain instances in the book, like where Kiera feels haunted and where her teenage daughter, Trista, might be pregnant, and also because of the language, Unbroken is just better for older, mature readers.
