I've been waiting for Marked in Flesh (The Others #4)! And I was the first person to check out my library's copy! I love this series and how it blends the typical urban-fantasy feel of regular folks mixed up with werewolves and vampires within the backdrop a unique world.
I can say without too many spoilers that the shoe we've been waiting for drops in Marked in Flesh. It will be interesting to see if this is the end, because the book finishes in a way that it might be the finale, or if the Book #5 listed in GoodReads for 2017 happens.
Please read this series in order. If you like fantasy or urban fantasy - I highly recommend that you give it a try.
