Cold Days: The Dresden Files by Jim Butcher

Orbit, 2012. ISBN 9780356500898.
Cold Days is another installment in the popular contemporary fantasy series which comprise the Dresden Files. Set in Chicago, Harry Dresden, the main character and narrator, pits his wits and talents as a wizard and private eye against dark forces that conspire to dominate the world. It's a complex society where fairies, ghouls, vampires and other spirits co exist alongside humans but interests often compete.
In this book, Harry has been forced into the service of Mab, Queen of Air and Darkness and she sets him an almost impossible mission: kill an immortal. Powerful forces are already working against him, threatened by his new role as Winter Knight. Harry has to find out why Mab seeks to destroy this target while constantly dodging plots against his own life. His investigations reveal the existence of a catastrophic threat and Harry must race against time and his own dark impulses to avert tragedy. He is joined by an assortment of friends and unlikely allies in this rollercoaster ride against evil.
Harry Dresden has an established legion of fans and this book will obviously delight them. The action is relentless and the stakes are always high. Harry is portrayed as an Indiana Jones type character in a contemporary Lord of the Rings setting. The book stands alone but familiarity with the strange world he inhabits is enriched by an awareness of the preceding books
