In this stunning ninth book in the New York Times and USA TODAY bestselling Keeper of the Lost
Cities series Sophie and her friends discover the true meaning of power—and evil. Sophie
Foster changed the game. Now she’s facing impossible choices: When to act. When to trust. When
to let go. Her friends are divided and scattered and the Black Swan wants Sophie to focus on
their projects. But her instincts are leading her somewhere else. Stellarlune—and the
mysterious Elysian—might be the key to everything. But finding truth in the Lost Cities always
requires sacrifice. And as the Neverseen’s plans sharpen into terrifying focus it appears that
everyone has miscalculated. The Lost Cities’ greatest lie could destroy everything. And in the
battle that follows only one thing is certain: nothing will ever be the same.
