Bound in Iron

When a new threat rises in Terrasen, Aelin and half her court suddenly disappear at the worst possible time. Somehow appearing in Faery and finding herself captured by the Winter Court along with Rowan, Manon and Aedion, will she be able to find her way home before it's too late?

Set after KoA, but for the sake of the story, let's just say Aelin and Dorian didn't lose their powers.
Set from the beginning of Iron Daughter, so Meghan is held captive by the Winter Queen.
