In City Of Bones, book one in The Mortal Instruments Series by Cassandra Clare, we meet Clary Fray a normal teenage girl who lives at home with her mother. One night she witnesses a murder, but cannot prove the crime because the victim disappears right in front of her eyes. She finds out later that the tattooed teens that murdered the boy are a group called Shadowhunters who kill demons. The strange thing is no one else can see them except for Clary. When she arrives home from the strange night she realizes that her mother has been kidnapped and the only way she can get her back is to find the Mortal Cup before it's to late. She finds herself becoming part of the shadowhunter world as she learns more and more about her and her mothers life. She also begins falling in love with one of them , Jace Wayland, a sarcastic teenage boy with the bad boy edge.
This is a easy read with some action, romance and suspense. I would recommend it to someone who enjoys not having to think to much while they read. You really get to know the characters and begin to feel like you have stepped into their lives.
