Dresden Files - Cold Days

Meet Harry Dresden, Chicago's first (and only) Wizard PI. Turns out the 'everyday' world is full of strange and magical things - and most of them don't play well with humans. That's where Harry comes in. A bargain made with the Queen of Air and Darkness has forced Dresden into a new job: professional killer. His first task is to bring death to an immortal. As if that wasn't hard enough, Dresden learns of a danger to Demonreach, the living island hidden upon Lake Michigan. A danger that could destroy billions and land Dresden in the deepest trouble he has ever known. Dresden has only twenty four hours to gather the allies he has left and prevent a cataclysm - all while the power he bargained to get, but never meant to keep, lays siege to his very soul.MAGIC - IT CAN GET A GUY KILLED.'The most reliable post-Buffy supernatural series on offer' Time Out
