The Iron Vow

Meghan and her companions have just leapt through a portal into Evenfall, a realm where Nightmares roam and glamour is almost gone. The group includes Ash, Puck and Grimalkin, and their goal is to track down the Nightmare King.

Their magic weakens the longer they stay. The creatures of Evenfall turn on them, so the search grows more desperate with each step. What they learn along the way overturns much of what they believed before.

The Nightmare King is stirring, and the fate of the Nevernever and the wider world depends on what happens next. Twilight is falling over every realm of Faery, and Meghan and her allies face one more choice with no easy answer.

This is the final book in the Iron Fey series, so it brings the whole cast together for the last time. It is a fantasy adventure with a fast, urgent pace, set in a hostile and darkening world where the heroes have lost much of their power.
