I read a lot of books last year and kept a little list as I finished each one and gave them a point rating. As the year closed I sorted them by rating looking for some really good titles I hadn't yet recommended. I finished out last year with the Grey Walker series by Kat Richardson. Set in modern day Seattle, the series features Harper Blaine, a P.I. who develops the ability to move through the Grey after dying for a couple of minutes and being revived. The Grey is the the realm of ghosts, vampires, witches, and magic that exists between our world and the next. Aside from this ability she's a very human and real-feeling character.
Harper is possessed of human flaws and foibles. She's touch too self centered: at one point when she has someone gunning for her, she hides out at the house of friends who have a little child. She does keep trying though, and learns from her mistakes eventually. The secondary characters are also well-developed. I'm really looking forward to seeing what happens to a certain major secondary character whose background and family history has been gradually revealed. (I fear giving out the secondary's character name would be too much of a spoiler for early books in the series.) Sadly, now I've got to wait until August 2013 for book 8. This is now one of my top ten favorite urban fantasy series.
