The Ninth Constellation
High above the valley, the bridges of Ardent Reach are held aloft by
sky-iron and the powerful upper wind. Engineer Nera Solen knows the
sound of every cable she has built—until one begins to sing an
impossible note. A failing bridge reveals that the city has been
trapping dangerous pressure while the villages below suffer the
consequences. With her apprentice and an unlikely coalition of
workers, Nera must uncover the hidden design and guide a perilous
release before the mountain city is torn apart.
