Gabrielle "Gabby" Smith, a 16-year-old prodigy from a war-torn dimension where people with powers are both rulers and weapons, has spent her entire life as a child soldier, trained by her parents — the authoritarian leaders of her world — to solve the ever-growing crises that plague their reality. A dancer by nature, Gabby mastered the delicate balance between grace and lethal force, honing both her acrobatic combat skills and her extraordinary ability to manipulate stellar energy.
