Tongue Eater - strange new worlds abound in Mage Errant Book 6
Hugh's world has been completely shattered. His teacher Alustin betrayed him and turned Hugh's pact with Kanderon into her downfall. He also stole the cruelest weapon their world has ever produced, the Tongue-Eater, which is capable of stealing a language and rendering its speakers mute for one or more generations. Sabae always suspected that they were a means to an end for Alustin, but not even she predicted his quest for revenge against the Empire would lead to such blatant treachery. With Kanderon presumed dead, and only one injured council member left, Skyhold is broken and leaderless. Hugh is convinced that Kanderon isn't dead and he is willing to do whatever it takes to help her, while his friends concoct a desperate plan to stop Alustin before he unleashes the Tongue-Eater. It's a plan that will literally expose them to multiple new worlds in the process.
