    Michael Davies is prepping to go to Pearl Harbor. Merope Ward is coping with a bunch of bratty 1940 evacuees and trying to talk her thesis adviser into letting her go to VE-Day. Polly Churchill’s next assignment will be as a shopgirl in the middle of London’s Blitz. But now the time-travel lab is suddenly canceling assignments and switching around everyone’s schedules. And when Michael, Merope, and Polly finally get to World War II, things just get worse. For there they face air raids, blackouts, and dive-bombing Stukas--to say nothing of a growing feeling that not only their assignments but the war and history itself are spiraling out of control. Because suddenly the once-reliable mechanisms of time travel are showing significant glitches, and our heroes are beginning to question their most firmly held belief: that no historian can possibly change the past.

    [Publisher's Note: The Mountains of Mourning was originally published as a stand-alone novella in the May 1989 issue of Analog. It was then included as the first of three novellas that make up the novel Borders of Infinity (October 1989). For the novel, Ms. Bujold added a short "framing story" that tied the three novellas together by setting up each one as a flashback that Miles experiences while recovering from bone-replacement surgery. Fictionwise is publishing these novellas separately, but we decided to leave in Ms. Bujold's short framing story for those who may also wish to read the other two novellas (Labyrinth and The Borders of Infinity).] Locus Poll Award Nominee, Nebula Award Winner, Hugo Award Winner, SF Chronicle Poll Nominee
