No matter where Cal Kinsey goes, danger always follows.

After being kicked out of his hometown by a hitman wizard with a strong vendetta, Calvin Kinsey is on his own for the first time in years. Without his job at DSI, he no longer has any legal protections to shield him from the wrath of his many supernatural enemies. And to make matters worse, he can't even speak to any of his friends without breaking the magic oath branded onto his arm. There is, however, one exception: Cooper Lee.

But when Cal's plans to meet up with the long-absent Cooper get sidetracked by an unexpected blizzard, he's thrust into the middle of a developing struggle in the snowy heart of Moscow. The Black Knights have smuggled a dangerous magic artifact into the city on behalf of their mysterious benefactors, and those benefactors will do anything to obtain this artifact-even if it means burning the entire city to the ground.

Teaming up with new acquaintances and old thorns in his side, Cal must navigate a perilous situation that pits him against the two types of people he fears fighting the most: those whose power he cannot overcome and those he once called allies.

Dawn Slayer is the seventh book in the action-packed City of Crows urban fantasy series.
