The atlas has been waiting for a name for two hundred years. Now it has one. At the deepest end of the library's oldest stacks, exactly where the founding gate took her in 1821, Fray's first partner is still there - mid-stitch, mid-reach, waiting the way every lost thing in this story has secretly been waiting: alive, and not gone. This time, Fray isn't going alone. A librarian who walked the dark. A Warder with a chalk line. An engineer with a metronome. A mother on the rope. A registrar who listened to a wall for two centuries. And one very determined girl - six threads instead of one, carrying together what nearly broke the world the first time it was carried alone. And when the rescue is done, the trade's oldest question finally gets asked: what does Fray choose to be, when she could have anything? The answer is the ending six books have been building toward. The final book of The Magic Carpet series brings the entire story together in a rescue two hundred years in the making, revealing the rug's deepest history and bringing six extraordinary threads together at last. A magical middle-grade fantasy finale filled with friendship, courage, belonging, hope, family, and spooky-but-safe thrills for strong readers ages 9-12. The last threadgate is here. Everybody home.
