This is the fifth book in The Dresden Files, the books about professional wizard Harry Dresden. This review may therefore contain some spoilers for books that came earlier in the series and also for this one, and you may want to skip it until you’ve read the books up to this point.
Harry has a number of difficulties facing him – his ex-girlfriend Susan (who Harry’s been moping over since she left him a few books ago) is back in town, getting ready to pack up her stuff to move to South America, and Harry is worried she may have found a new guy. A powerful Red Court vampire is also in town, challenging Harry to a duel, to settle once and for all the bad blood (pun intended) and warfare between the wizards and the Red Court once and for all. If Harry refuses to duel, the vampire will hunt down and kill anyone Harry cares for or has worked with, so he’s not really got much choice in the matter. Thirdly, a priest wants to hire Harry to look for the stolen Shroud of Turin, and it seems like there are demonic entities who’d like nothing better than to find the artifact first, so they can unleash a devastating plague on humanity. The rest on my blog.
