  We show that the facet-ridge graph of a shellable simplicial sphere $\Delta$
uniquely determines the entire combinatorial structure of $\Delta$. This
generalizes the celebrated result due to Blind and Mani (1987), and Kalai
(1988) on reconstructing simple polytopes from their graphs. Our proof utilizes
the notions of good acyclic orientations from Kalai's proof as well as
$k$-systems introduced by Joswig, Kaibel, and K\"orner.
