I recently read this series and I would definitely recommend it to any fan of the Twilight series. It has vampires in it, albeit they don't play a huge part, but they are present. The book is about 15 year old Clary Fray and she is trying to find her place in the world when her mother suddenly disappears. Who is this new guy she's met, Jace Wayland and his friends?
This book has action, romance, vampires, werewolves, and the main species which is Shadowhunters. Great series, maybe a little bit more for the mid/older teens than the younger ones. 
PS: this book has 2 more, making it a trilogy. Easy reads, the level is not to difficult making it enjoyable.
GREAT. Seriously anyone would like these; they open a whole new world. The characters are amazing, its not ever boring (you'll actually need a breather here and there), its hilarious, there's love, action and basically this series is just plain engrossing. You'll never be disappointed trust me 
Oh and they're my all time favorite books as of now.
