The breathtaking conclusion of the popular fantasy quartet by acclaimed author Tamora Pierce.<br><br>Kethlun Warder was a gifted glassmaker until his world was shattered in a freak accident. Now his remaining glass-magic is mixed with lightning, and Tris must teach him to control it (if she can teach him to control his temper first) . But there's more at stake than Keth's education. With his strange magic, he creates glass balls which reflect the immediate past and expose the work of a murderer. If he can harness his power properly, he'll be able to see the crimes as they take place. Keth and Tris race against time and the local authorities to identify a killer who's living in plain sight.
