"Dark Rock" by Mongolian writer, Dashdorjiin Natsagdori, begins with what appears to be a failed mnemonic in a diary, "Saturday, August 30. Dark Rock. Nina." He believes it may have been a reminder from a long lost love, and as it happens to be Saturday, August 30, he supposes that they were suppose to meet today, but exactly where is even more cryptic. He sets out in search for any place that might be considered Dark Rock.
I'll try not to give it away, but I'll say that it occurred to me sometime after reading it how much it reminded me of Edgar Allen Poe's "The Raven." Nina is Lenore, the dark rock could, perhaps, be the raven, and nevermore is Saturday, August 30. Though that last one changes the entire state of affairs, I can't decide if it's more or less hopeless than Poe's.
