The world knew of three special children - the Angel-blooded ones, Clarissa Fairchild and Jace Herondale, and the demon-blooded one, Sebastian Morgenstern.
But there was another one - a child with an angel's heart but demon's blood. There was another child with superficial strength, agility, speed, grace, special talents and an invincible physique.
Her name was Leah Ravenscar - one of the six heroes who had helped save the world.
And she was the illegitimate daughter of Tessa Gray and Brother Zachariah.
Sequel - Leah Carstairs - is out now!
