I just picked up The Traitor by Anthony Ryan (release the other day). So far I really like the Covenant of Steel series. So I can't wait for the next installment after this.
Also the next Dresden book is always on my must have list.
Book 17 'Battle Ground' is way better than the previous. But I am hoping for a stellar ending. We have got to read along as Dresden struggled to adapt and grow and he is finally one of the most badass Wizards on the planet if not the most badass Wizard. The end is near and I hope it's good. I suspect Butcher will wrap it all up with a nice little happy ending because a lot of fans would be upset if he GoT Dresden in the end.
