in third grade at Ari's school their literature unit is the chronicles of narnia by c.s. lewis. the second book is the lion, the witch, and the wardrobe. when each member of the class has completed that book they have a special day where everyone gets to "enter the wardrobe".
"If the witch understood the true meaning of sacrifice, she might have interpreted the Deep Magic differently, for when a willing victim who has committed no treachery, dies in a traitor’s stead, the stone table will crack and even death itself will turn backwards." Aslan, King of Narnia
