Dear Bob — “Dear Bob.” I can’t believe I’ve written that. Did I ever think you’d read this letter? Dear Bob — Dear Bob!!! I’ve done it. I’m writing the letter. How are you? But I won’t know that, will I? Not until I read your letter. Don’t forget—put it where you found mine, between Asimov and Bester, fourth shelf up in the science fiction section of Cray Point’s library, just as we agreed. I’ll pick it up when I’m next through, I promise, and God willing, I’ll leave you another letter that day. Then we’ll swap letters, just like that couple in 84 Charing Cross Road, swapping our lives between the lines.

Though Marietta’s eyes are closed, she is wide awake, fingering the new sheets she gave Asher as part of his six-month anniversary present. The other parts were dinner, followed by multiple sexual favors. She has already thought ahead, to the seven-month anniversary, when she will trade dinner for breakfast, trade a languorous night of sex for a quickie. She worries about thinking so far ahead and having expectations concerning things she cannot fully control. Is this really the way being in love should feel?

Dan Linh had walked out of the Purple Forbidden City not expecting to return to it—thankful that the Empress had seen fit to spare her life; that she wasn’t walking to her execution for threefold treason. Twenty years later—after the nightmares had faded, after she was finally used to the diminished, eventless life on the Sixty-First Planet—she did come back, to find it unchanged: the Midday Gate towering over the moat; the sleek ballet of spaceships between the pagodas and the orbitals; the ambient sound of zithers and declaimed poetry slowly replacing the bustle of the city at their backs.

It was difficult to sleep at night, wishing good men dead. This was but one of the hurtful things I felt in my bones and wished I could ignore. It was an ugly truth waving its arms that I turned my gaze from, that I didn’t like to admit even to myself. But while my bag warmed me with the last of its power and my breath spilled out in white plumes toward the roof of our tent, while the flicker of a whisperstove melted snow for midnight tea, I lay in that dead zone above sixty thousand feet and hoped not just for the failure of those above me, but that no man summit and live to tell the tale. Not before I had my chance.

Wren Hex-Yemenni woke early. They had to teach her everything from scratch, and there wasn’t time for her to learn anything new before she hit fifty and had to be expired. “Watch it,” the other techs told me when I was starting out. “You don’t want a Hex on your hands.” By then we were monitoring Wren Hepta-Yemenni. She fell into bed with Dorado ambassador 214, though I don’t know what he did to deserve it and she didn’t even seem sad when he expired.
