Terrier by Tamora Pierce

In the lawless Lower City of Tortall, young Beka Cooper begins her training as a Dog—one of the realm’s guards sworn to keep order where crime rules the streets. Gifted with the rare ability to hear the voices of the dead through pigeons and dust, Beka is determined to prove herself. As she uncovers a series of kidnappings and murders linked to powerful forces, she risks everything to bring justice to those forgotten by the law. Terrier introduces a fierce heroine whose courage and loyalty blaze against the darkness of corruption and danger.
