The Company of Seven - Kron Darkbow, #6

An undead mage thousands of years old slinks through the city of Bond. Rising up from beneath the soil, he soon finds himself allied with escaped fugitives from the Prisonlands, a former knight, a pair of assassins and the chief of thieves. Each has their own wants, their own goals, but the wizard's are the most deadly to the citizens of Bond, and he refuses to be denied his destiny. Spotting healer and wizard Randall Tendbones as a threat, a plan is soon hatched to remove him permenantly, but swordsman Kron Darkbow might have something to say about that.
But Tendbones is only the beginning, for the murder of thousands is in the works, and unless Kron can put a stop to the terrors stalking Bond, the devastation will reach across all levels of the city and beyond.
