Some writers can write great fantasy, but most can’t. Diana Wynne Jones is one of the former. J. K. Rowling may have the money and the fame, but I consider Diana Wynne Jones to be the greater fantasy writer. Her body of work maintains a high standard of quality. If you haven’t read any Diane Wynne Jones, here is a good place to start. In Deep Secret the “Multiverse” is in danger of becoming unbalanced and only the efforts of the Magids–powerful magicians who can move among dimensions–can prevent disaster. The battle continues in The Merlin Conspiracy as a page, Arianrhod Hyde (Roddy), finds herself in the middle of a conspiracy that could destroy worlds. Strong writing, plenty of action, intricate plotting, and deft characterizations blend into compulsive reading at its best. Sometimes, Diana Wynne Jones’ books are shelved in the YA section of the library or bookstore. Don’t be fooled! There’s plenty of delight here for precocious teenagers and discerning adults alike.
Normally I don’t read this genre but you’ve convinced me that if I’m going to read fantasy to start here. I have a sister who does and her b-day is around the corner and Diana Wynne Jones sounds perfect. Thanks.
If somehow Diana Wynne Jones isn’t to your taste, other great fantasy writers are Michael Moorcock and Robert Bloch. I’m sure your sister will love any of Diana Wynne Jones’ books.
Howl’s Moving Castle was made into a great movie by Miyazaki.
Castle in the Air and The House of Many Ways, the sequels to Howl’s Moving Castle are also very good.
Naturally, everyone has their own preferences and tastes in fantasy. I’ve read a couple of Jones’ books and they’re okay, but there’s a reason she’s shelved in the YA section: it is YA fantasy. For “meatier” fantasy with more depth, stronger characterization and plot I’d recommend Eddings, Kurtz, Martin, Rowan, McKiernan, Daniel Hood, Dave Duncan and others.
I’m also a fan of Jack Vance’s fantasies.
