NEW YORK TIMES bestselling author Tamora Pierce takes readers to a world filled with adventure and magic.
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 that 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.
Tamora Pierce closes her The Circle Opens quartet of fantasy novels with Shatterglass. Tris, the weather mage introduced in the previous series, Circle of Magic, now travels to Tharios, where a glassmaker's magic may help him identify a serial killer-if Tris can teach him how to use his power.
