Haruki Murakami's 1Q84

Haruki Murakami (村上 春樹) is a terrific writer and I'm excited about his new book 1Q84.

And this article about the book jacket makes it sound even better:
The plot follows two seemingly unconnected stories that eventually weave together. The first involves a woman named Aomame, who in the opening scene finds herself descending a service staircase off a busy elevated highway in Tokyo to escape a traffic jam. Once she gets to the bottom and out onto ground level, she eventually comes to believe that she has entered an alternate reality, one only slightly different than what she had known. She refers to this new dimension in her mind as 1Q84 (the book takes place in 1984 and in Japanese ‘Q’ sounds just like ‘9′), with the Q standing for “Question Mark. A world that bears a question.” This concept becomes one of the novel’s major themes.
