The Knight and The Red Cloak (Knights of The Compass #2)
Dru Wellington

Noel, dressed in his late father’s red cloak, is asked by the king to keep him in hiding and perform one task, a task that Noel wishes he could refuse. But doing so would condemn his kingdom to King Maas’s vicious hand.
No choice but to prepare a potion that will kill the king of the West, Noel hunts for ingredients in the deep, dark woods. Woods Noel thinks he knows like the back of his hand . . . until he meets a Wolf that leads him astray.
