Phantom Pains (TotP Book 3)

When Cayde was killed, Skylar had to learn how the world worked without him. On Europa, her clan is faced with the fact that the Light can't save humanity, and standing by and doing nothing isn't an option. When the Bray sisters contact her about something that could bring Cayde back, her world is torn open. The universe isn't done with them yet, and maybe the Traveler never was.
