Every winter solstice, today’s earthly descendants of Greek gods, nymphs, and muses must visit Mount Olympus to preserve their near-god status. Until Dorothy’s mother refuses to go, sealing her fate and dying a human death shortly after. In retaliation, the gods release an ultimatum: return to the heavens as gods or live as humans on earth. Without her mother, the rest of Dorothy’s world becomes quieter, stiller—and her grief threatens to consume her. Apple, on the other hand, is the beloved descendant of Zeus and Hera. The two girls couldn’t be more different, but their mothers were best friends, and now they finally grow closer, too. Yet as the solstice nears, Apple’s fear of losing Dorothy causes her to make a choice for them that changes everything—and the consequences are great.
