Death Masks - Jim Butcher

Death Mask is another Dresden Files novel.  This time Harry is up against the vampires of the Red Council and the Denarians.   Denarians are half demon and half human and all mean.  Not something you want to run into in a dark alley or anywhere else.  And Susan is back.  That makes things even more complicated.  As usual more action and suspense than three other average books.  Highly recommended.
