Harry Harry Harry Dresden. He's getting on par with Lucas Davenport in the characters I'll follow everywhere.
Turn Coat is the 11th book in the Dresden Files. Harry Blackstone Copperfield Dresden is a wizard/PI. He helps out the Chicago PD when weird things happen that no one can explain or no one wants to acknowledge. Harry is a member of the White Council and a Warden (big deal in the magic world). His nemesis, Warden Morgan, ends up on Harry's doorstep bleeding and begging for his help. Harry, being the nice guy he is, shelters Morgan and does his best to help him prove his innocence against some trumped up murder charge.
Captain Luccio is back and still hot and heavy with Dresden....but this ends in a plot twist that I didn't see coming. Molly is back as Harry's apprentice and is helping to protect Warden Morgan. A new Big Nasty is introduced in the form of an ancient skinwalker. A shape shifting beast that seems to be indestructible.
Turn Coat is on of my favorites in the Dresden series. It was fast-paced and introduced quite the boatload of new plot twists that will (hopefully) be carried forward into the rest of the series. One beef: Michael was injured badly in the last book, but Turn Coat only devotes one sentence to how he is. Tying up that little loose end would have been nice.
