Jim Butcher’s Dresden Files is one of the best selling and most beloved fantasy sagas on the shelves. How can a series that is now 25 years old with 17 books on the selves stay fresh? Well, one way is to change up* how the story is told. Jim Butcher has said that a Dresden Files novel is essentially the worst weekend of the year for the only wizard in the Chicago Yellow Pages. Well, the title says it all – Twelve Months. Unlike any other novel in the series (mild exception to that rule would be Cold Days which cover a little more than Butcher’s allotted “weekend), the 18th novel in the series takes place over the course of a year. But that kind of pacing and consideration in the story itself is a welcome respite from the chaos of the last two novels and the largely breakneck pace of the last third or so of the series. I’ll say this and get it out of the way, this is one of the best Dresden Files novels and some of the best writing of Butcher’s career (that I’ve read).

One year. 365 days. Twelve months.
Harry Dresden has been through a lot, and so has his city. After Harry and his allies narrowly managed to save Chicago from being razed to the ground, everything is different—and it’s not just the current lack of electricity.
In the battle, Harry lost people he cared about. And that’s the kind of loss that takes a toll. Harry being Harry, he’s doing his level best to help the city and his friends recover and rebuild. But it’s a heavy load, and he needs time.
But time is one thing Harry doesn’t have. Ghouls are prowling Chicago and taking out innocent civilians. Harry’s brother is dying, and Harry doesn’t know how to help him. And last but certainly not least, the Winter Queen of the Fae has allied with the White Court of vampires—and Harry’s been betrothed to the seductive, deadly vampire Lara Raith to seal the deal.
It’s been a tough year. More than ever, the city needs Harry Dresden the wizard—but after loss and grief, is there enough left of Harry Dresden the man to rise to the challenge?
The previous novel in the series, Battle Ground was perhaps the most emotionally devastating novel since Changes. Things have changed drastically for our wizardly friend and in a lot of ways, he’s in a place hasn’t been in many years and is at a major crossroads, especially from an emotional perspective. Twelve Months is a novel about pain and loss, trying to come to grips with one of the most devastating things a person can experience. While the Battle of Chicago may have been a victory for the good guys, it was a bittersweet victory in many ways. I’m trying to walk the line of not spoiling Battle Ground because as I sit with this novel more, I feel it would be an interesting experiment to be read as a standalone.
The loss Harry is suffering attempting to cope with is compounded by an arranged marriage to Lara Raith, of the White Court of Vampires. She also happens to be the sister to Harry’s half-brother Thomas Raith and Thomas is in a predicament from which Harry is trying to save him. This betrothal to Lara is at the behest of Harry’s liege queen and ultimate boss, Mab, the Queen of Air and Darkness, the Winter Queen. A lot of the turmoil in this novel, the conflict, involves Harry trying to trust one of the most powerful vampires in the world (traditionally enemies of wizards and The Wizard Council), continuing his inner quest to become a better person, following the orders of Mab, while dealing with the most painful loss he’s ever suffered. Yeah, Harry may not be physically thrown about and beaten up like he often is in these novels, but he is emotionally wrecked and attempting to recover and be close to his former self as possible.
Helping Harry to “find himself” are his former apprentice and Winter Lady, Molly Carpenter; Molly’s father and one of Harry’s best friends, Michael Carpenter, Knight of the Cross; Harry’s focus on trying to save/redeem his half-brother Thomas; Harry’s daughter Maggie; and even his grandfather Ebenezer.
Even Lara Raith. Even Mab, who is often very much at odds with Harry. Sure, she is quite strict as is her nature in that she is something of a rule monger. But Mab needs her Winter Knight to be strong – physically, mentally, and emotionally.
Twelve Months… it is a long time to be in Harry’s head and gives Butcher the opportunity to show a cumulative growth and more thoughtfulness than we’ve come to expect from Harry and this series. Again, I loved what Butcher did; both in the what he wanted to do and how he executed his plan for the novel. Giving this novel a year’s worth of time also allows for a fascinating way to explore Harry and Lara’s relationship. We as readers are conditioned to not trust vampires, largely because Harry is our first-person narrator, but she came across as very genuine in her actions and conversations with Harry.
This maybe seen as a “transition novel” for the series by some and maybe it is. For me, I’d consider it one of the most important novels in the series. It is a book that shows a writer who is willing to take risks this far into his career and with a series that means so much to so many readers. I love this series and this book moved my emotions as much and more than some of the previous installments. I hope fans of the series enjoy Twelve Months as much as I did and I’d even be interested to learn of any readers who decide to give the series a try with this installment.
Highly recommended.

I was so mad at what Butcher did with a very important character in the previous book that I’ve seriously considered giving up on the series. The relatively big gap between books didn’t help either… Maybe I’ll check it out if my local library has it.
