Galaxy: The Prettiest Star #1

Every day in Taylor Barzelay's life might seem perfect…but every day is torture. Taylor is actually the Galaxy Crowned, an alien princess from the planet Cyandii, and one of the few survivors of an intergalactic war. For six long, painful years, Taylor has accepted her duty to remain in hiding as a boy on Earth. But that all changes when Taylor meets Metropolis girl Katherine "call me Kat" Silverberg, whose confidence is electrifying. Suddenly, Taylor no longer wants to hide, even if exposing her true identity could attract her greatest enemies.

Characters: Argus (Robot), Galaxy, Kat Silverberg
