The Nel Mezzo Series

While Celeste battles monstrous external foes, there are also inner demons she must face. As the biracial teenage daughter of mixed-faith parents, Celeste suffers from acute introversion—and an inablilty to find her place in the world. Her only escape is immersion in the virtual reality games her father designs. But it's through the guise of gaming that Celeste is forced to overcome her sensitivity by accepting it as being the gift that makes her a heroine.
