#4 City of Ghosts. Stacia's third book in the Chess Putnam series is a wonderful read, full of suspense and lot and lots of steaminess between Chess and Terrible (wink, wink...love me some Terrible!). In the first book I really had to concentrate to get the feel for the Downside's unique language. It threw me for a loop at first, but once it clicked in my head then I couldn't imagine it any other way. It fit the scenes perfectly and by book #3 it was as if it was a normal thing.
If you are into dark urban fantasy, then you definitely need to pick up all three books. Stacia's books have been my first experience with it and Chess's adventures do not disappoint. I'm on pins and needles now as I wait on number four in the series so hurry up with it Stacia!
