City of Ghosts - Stacia Kane
So... the ridiculous thing? Ever since I finished Shadowfever in March 2011, I've been searching frantically for an adult series that was about more than just romance and sex, an urban fantasy series that was actually well-written with a good mystery going on. I have now finally found that well-written urban fantasy series + mystery and all I can think about is "when will Terrible show up and - more importantly - will there be sexytimes?!"
