Subtle Blood

This was a nice bow to tie up the series with. The two main characters are definitely some of my fave and the pulp murder mystery plots were really well executed.
While it's a bit bittersweet the series ended here, it would have probably gotten a little repetitive. This final book, while just as good as the first two, was kind of a rehash of the arc over the previous books in that Zodiac, the criminal enterprise Kim has been fighting against, was disbanded after the death of their leader but the bureau had yet to capture them all and surprise! they're back to cause more mayhem. The series could have definitely ended in two books but since I like the author and these characters so much I'm glad it didn't.
There isn't much more to say. KJ Charles is one of the best writers in the MM historical genre and I can't wait to see what's next.
