Shard axe, the

Sentinel Marshal Sabira d'Deneith has spent the last eight years trying to drown the memories of the mission that cost her partner his life and gave her the nickname "The Shard axe." Until she's recalled from the city of Stormreach to carry out a mission on House Deneith's behalf--protect and defend the heir of the dwarven city of Frostmantle during his murder trial. The same heir she and her partner guarded eight years ago in the same city--from the same style of murders. Is the dreaded Nightshard still alive and taunting her? Or is there another serial killer loose in the Mror Holds?
