After the devastating events that nearly destroyed Chicago, Harry Dresden is struggling to rebuild both his city and himself. The battle may be over, but the emotional scars remain. As Harry copes with grief and loss, new dangers quickly emerge.

Ghouls are hunting innocent civilians across Chicago. Harry's brother is dying, and no magical solution seems within reach. Meanwhile, a dangerous political alliance between the Winter Court of the Fae and the White Court of vampires leaves Harry facing an unwanted engagement to the powerful and deadly Lara Raith.

With powerful enemies closing in and impossible choices ahead, Harry must discover whether he still has the strength to protect the people he loves—and whether the wizard can save the man beneath the magic.
