What is a war of gifts?

The War of Gifts is a novella by Orson Scott Card, published in 2007 as part of the Ender's Game series. It takes place during the events of Ender's Game and Ender's Shadow, two other novels in the series. The novella focuses on a conflict between students at Battle School, a training facility for child soldiers, who are prohibited from celebrating religious holidays. A group of students, led by Zeck Morgan, push for the right to celebrate Christmas, while another group, led by Dink Meeker, opposes them. The conflict escalates into a full-blown "war of gifts," with each side vying for control of the school and the minds of their fellow students. The novella explores themes of freedom of religion, cultural diversity, and the moral implications of war.
