Ottilie Colter and the Withering World: Volume 3

"Ottilie and her friends are members of the Narroway Hunt, a secret organisation that trains children to kill bloodthirsty monsters called dredretches. Now, the huntsmen are under attack by something far worse than dredretches. A witch is cursing them one by one, making them unwilling participants in a vengeful scheme. But what, exactly, is she planning, and will Ottilie have to join her to find out?"--Publisher's description.
