Summary
Alec is half shadowhunter half warlock. First time he showed his warlock mark was when he was only 5 years old. His parents disowned him and portaled him to the London and let him on the street to die.
Few days later Ragnor Fell sees demon attacking him and there is a shield around the little boy. Ragnor kills the demon and takes him home and decides to raise him.
15 years later thanks to his dad (Ragnor) Alec is embracing who he is. But one day he finds his dad’s house broken into and Ragnor nowhere in sight! And now some shadowhunters and warlock is searching for Alec saying they need the book of the white (because he is the one who hidden the book). Yeah, good luck finding it because he trusts NO ONE, especially not Shadowhunters!
