Marked is an action packed, page turner. The story follows a girl named Kara, age 16. After getting flattened by a bus on her way to a meeting with one chance to get a scholarship, she becomes a guardian angel. GA's (guardian angels) protect mortals' souls from being eaten by demons. GA's are NOT alive. They do not have a beating heart. They stay connected to the Horizon by mortal souls living. This book was added to my top 10 list yet it does depend on the reader. I recommend this book and rate it five out of five stars. Read the book to find out about Kara and her adventures! ENJOY!
