Cold Days by Jim Butcher

In yet another engaging urban fantasy that leavens apocalyptic threats with smart-ass humor, Butcher just keeps upping the ante for wizard Harry Dresden, appearing in his 14th novel after 2011’s Ghost Story. Being killed has barely slowed down the Chicago PI, who now serves as the Winter Knight. In that role, Dresden operates as hit man for Mab, the queen of air and darkness, who is forbidden from killing mortals. Not only is his liege capricious and deadly, but Dresden soon finds himself up against new supernatural foes, not least the Redcap, who dyes his headgear with the blood of anyone unfortunate enough to cross his path. The greatest danger, however, may be from Dresden’s new assignment from Mab: to murder her daughter, Maeve. Plentiful backstory allows newcomers to have little trouble getting caught up in the action or connecting with the charismatic lead. –Publishers Weekly
