Changes is the twelfth book in the Dresden Files series by Jim Butcher and true to the title this is the book where many things change and the book ends in a cliffhanger. In this one we find out that Susan Rodriguez, Harry’s one time lover, who earlier in the series was turned into a partial vampire had a daughter with Harry and never told him before now. She has been kidnaped by Arianna Ortega, Duchess of the Red Court, in a bid to harm Harry and he will do what ever it takes to save his daughter.
Changes is where plot elements and information that both Harry and the reader have gained though out the series is brought together and we see how far Harry is willing to go for those he cares about. It is also clear with that ending that the series will be different in some ways going forward.
Personally, while I liked see how many things are coming back I overall didn’t enjoy this book. That is mostly because I was never a fan of Susan and her relationship with Harry. However, with how it ended I definitely will be continuing with the series.
