If you don’t follow Jim Butcher on Twitter yet, you may have missed the exciting announcement that the first chapter of the next novel in The Dresden Files series Changes will be going live on Jim-Butcher.com tonight at midnight EST. Changes is the 12th book in the series and from the plot description sounds like it’s going to be one heck of a book:

Long ago, Susan Rodriguez was Harry Dresden’s lover-until she was attacked by his enemies, leaving her torn between her own humanity and the bloodlust of the vampiric Red Court. Susan then disappeared to South America, where she could fight both her savage gift and those who cursed her with it.

Now Arianna Ortega, Duchess of the Red Court, has discovered a secret Susan has long kept, and she plans to use it-against Harry. To prevail this time, he may have no choice but to embrace the raging fury of his own untapped dark power. Because Harry’s not fighting to save the world…

He’s fighting to save his child.

The novel comes out on April 6th and you can currently pre-order it on Amazon!
