Ajax Penumbra 1969 Publisher's Summary

From Robin Sloan, author of Mr. Penumbra’s 24-Hour Bookstore, the story of Mr. Penumbra’s first trip to San Francisco - and of how he got entangled with the city’s most unusual always-open enterprise….

It is August 1969. The Summer of Love is a fading memory. The streets of San Francisco pulse to the sounds of Led Zeppelin and Marvin Gaye. And of jackhammers: A futuristic pyramid of a skyscraper is rising a few blocks from City Lights bookstore and an unprecedented subway tunnel is being built under the bay. Meanwhile, south of the city, orchards are quickly giving way to a brand-new industry built on silicon.

But young Ajax Penumbra has not arrived in San Francisco looking for free love or a glimpse of the technological future. He is seeking a book: the single surviving copy of the Techne Tycheon, a mysterious volume that has brought and lost great fortune for anyone who has owned it. The last record of the book locates it in the San Francisco of more than a century earlier, and on that scant bit of evidence, Penumbra's university has dispatched him west to acquire it for their library. After a few weeks of rigorous hunting, Penumbra feels no closer to his goal than when he started. But late one night, after another day of dispiriting dead ends, he stumbles across a 24-hour bookstore, and the possibilities before him expand exponentially....

But after just a few days on the job, Clay begins to realize that this store is even more curious than the name suggests. There are only a few customers, but they come in repeatedly and never seem to actually buy anything....
