By now it's become a law of nature: another Dresden Files novel by Jim Butcher, another extraordinarily good read. The advenutres of Mr. Dresden, the only wizard in the Chicago phone book, just roll along as if the law of diminishing returns didn't exist.
Changes is no exception. Butcher's blend of humour and drama, magic and noir grit, and simple humanity [for all its graces and ills] still works. Think the first dozen or so Spenser novels by Robert B. Parker. Now add a unique and detailed set of rules for magic, complete with dire consequences for attempted misuse. Stir in all of Faerie, several different brands of vampire [ruled by various Courts], werewolves and the like and add apocalyptic stakes and you have an idea of both the grandeur and mire that inhabits this novel.
The plot is simple: one of the leaders of The Red Court [see vampires] plans to cast a bloodline spell that would remove all of Dresden's line from existence. Since, to his knowledge, that means the daughter he's just discovered exists, he must prevent the spell from taking place - and, oh, yeah, save the world.
He'll get no help from the governing body of wizards, The White Council, but there's always sympathetic cop, Sgt. Karrin Murphy [who packs a lot of smarts and tough into her five-foot nothing frame], his vampiric half-brother, Thomas [long story, don't ask - read the books] and the mother of his child, Susan Rodriguez [whom he'll hate for not telling him about his daughter - but not until after they prevent the spell].
If you haven't read any of Butcher's work [he also has a brilliant epic fantasy series, the Codex of Alera], pick up the first Dresden, Storm Front, and proceed through the series until you hit Changes. You'll be glad you did.
