This is the first book in the Mortal Instruments series by Cassandra Clare.
The story centres around Clary who is 15 and has never really quite been able to fit in before, she has always felt like something was missing from her life.
Turns out Clary is a Shadow Hunter, who for generations have protected the human world from the invasion of demons, she has been lied to her entire life by her mother about her heritage. Clary sets out to find out for herself what exactly being a Shadow Hunter means and to gain back lost childhood memories of this exciting new world.
On the way she meets Jace, a fellow Shadow Hunter who helps Clary with her decisions and memories.
This book is full of twists and turns and there is plenty of action throughout. I really loved Cassandra's writing style, and most of time felt like I was right there inside the book with the characters. The character descriptions are wonderful, which makes the reader feel even more connected to them, and in my case fall in love with them!
