There’s no rest for the wicked or the good, so Lily, Sebastian, and Sir Kipling’s have to hit the ground running as they regroup from their crippling battle with Nergal and search for the fabled city of the ancients. Only they know the threat Nergal poses, and they must race across the world to find the city and warn the inhabitants before this prince of demons destroys it all. But they can't do it alone. Thrown together once again with the fae of Melthalin and Lily's own murderous, conniving father, they'll have to navigate waters so treacherous that one misstep could kill them all. Long-held secrets are coming to light, secrets that could destroy everything they hold dear. Including each other.
