By Peter Dickinson.
This book picks up with the epilogue to The Ropemaker repeated as a prologue: Saranja returning home 20 generations after the events in the first book, and finding herself on an adventure very similar, at first, to the first one. The feel of the writing is also quite similar, although with more romance and string theory. However, the world described still feels like it mostly doesn't exist (i.e., doesn't have a history or people doing things outside of the narrative). outside of what happens in these books.
The use of Maja, an 11 or 12-year-old girl, as the main point-of-view character is particularly interesting because of her vulnerability to frequent blackouts. Unlike Tilja in the first book, who had a special immunity to magic, Maja doesn't see everything of importance that happens, and important events often happen while she is asleep or passed out, although she is still vital to the quest.
This book can probably be read alone without missing too much, although there are references to the events of the first book. I have no idea what to recommend it as; despite the size, it's a fairly light read with a flat villain and a not-too-memorable plot. Somewhat enjoyable, but not very deep.
