A slow start and a very satisfying end. A short story that encompasses space travel, prophecy, stars, family, love, and memory.
Sisters, Callisto and Pallas, bound together for life. Would they still be, if not for a prophecy? Would their actions be the same, if not for the prophecy? Are prophecies self-fulfilling as a rule?
Speculative in a different sort of way, and tying in with the theme of identity that (I feel) features in all the stories in this issue of Clarkesworld.
