Long-awaited by whom? Good question.
I'll break it into categories:
Reading
I'd recommend the books I've read this December, The Paris Enigma, by Pablo de Santis (an Argentinian writer), and Atmospheric Disturbances, by Rivka Galchen. Both books have "genre" elements to them, but neither is, narrowly speaking, a genre novel.
The de Santis book concerns a narrator who reads about the exploits of The Twelve, a group of world-famous detectives from various parts of the globe. He apprentices himself to the Argentinian member of the group and, due to that detective's final and most morally problematic case, he fills in for the detective at a meeting of The Twelve in Paris for the World's Fair. There, mysteries abound, implicating and affecting the other detectives. The book presents a classically styled mystery to solve, but it also asks questions about the role of "the enigma" in one's life, and how, in Heisenbergian fashion, the observer of the enigma becomes its co-creator. Really a terrific story and, assuming one can judge on the basis of a translation, well told.
Galchen's novel builds its narrative with a series of science fictional ideas: a doppelganger, parallel worlds, international conspiracies, the fluid nature of reality. I don't want to spoil the book for anyone, but it's clear from the beginning that something's "off" with our narrator, a husband who is convinced (and obviously this makes no sense) that his wife has been replaced by a duplicate. How he's come to this realization, the events in his life that set him up for these circumstances, and the steps he takes to locate his "real" wife--this is the structure of the story, which I found entertaining and well written. A fine first novel.
I am presently reading a few things: Paul Auster's Man in the Dark, which is not impressing me, but I only have 60 pages to go; Jay Parini's Promised Land: Thirteen Books That Changed America, which would be a great basis for a history or humanities class; and Art Objects: Essays on Ecstasy and Effrontery, by Jeanette Winterson--I'm finding that I have to stop after every few paragraphs to just soak in Winterson's observations and thoughts; it's brilliant, so far; I highly enjoyed her bravura novel Written on the Body earlier this year.
I've also been reading short fiction by Ben Fountain and learning more about Robert Frost's poetry.
Writing
There's less of this during the school year than during the summer. I am mostly finished with a draft of a story called, at the moment, "Helping Them Take the Old Man Down." I did not, until a few days ago, see it as a genre tale, but it could probably fit quite easily at Asimov's or F&SF. The draft is 7,500 words, but it's not complete, and the whole thing needs to be organized and then studied for repetition; I wrote scenes and fragments and lines largely without regard to their order, as things occurred to me.
I do occasionally make forays into my novels, planting a line here and there for place-holding until my eventual return. The novels are The Drowned Book and the somewhat fantastic In the Deep Woods Where I Found Her. I'm looking forward to getting back to them.
School
With very little effort, you can find the two blogs and schedules I keep for my school courses, an 8th-grade English class and a film studies class called "The Language of Film."
