Being the goddess of night is not as easy as it seems-after all, Nyx is in the constant shadow of Eos, Goddess of Light. When Nyx has the chance to go to MOA as an Unsung Hero, she thinks she can finally shine in her own way. But Principal Zeus is so scared of the darkness Nyx brings, he still sleeps with a nightlight! And her arrival seems to bring on more nightmares than sweet dreams. Can Nyx convince everyone that a little darkness is a good thing?
