Blood Rites by Jim Butcher

Dresden Files 6, here we go. This feels a bit like a watershed book for the series. Up to this point, the overarching plot, established from book three, is that the wizards are at war with the Red Court of vampires. Thus far, this has been a bit of a cold war, and its only really been mentioned in passing during the books since then; it wasn’t 100% clear whether Butcher was going to fully commit to this as a major plot point, especially as bits and pieces of the previous books were looking at ways that either side might be able to get out of the war with their honour intact. However, from Blood Rites, it definitely feels like the Red Court war will remain a major plot point going forward.
