THE EXPERT OF SUBTLE REVISIONS
by Kirsten Menger-Anderson
Crown, March 2025
In Half Moon Bay, California, 2016, a young woman waits for her father’s sailboat to arrive at port. They have agreed to meet on this day and time. Yet he never shows. He had told her this day might come. And if it did, she was ready. Go to the library in Berkeley, find a certain book, follow the instructions. But what if the instructions lead to more questions than answers?
In 1933, a young man arrives in Vienna to begin a new post as a professor of mathematics at the University. There he finds himself part of the Engelhardt Castle, a group of intellectuals that have recently been dubbed a target by a growing, anti-academic mob. The circle includes the preeminent minds of their time, and a cast of characters desperate to get invited into their midst, many of whom will stop at nothing to get there. As fascism rises, and polarization increases, moderate voices are drowned out. There are whispers of a machine, a music box, which can transport someone through time. But no one can confirm if it’s a rumor, or true. And the only people who know first-hand are not talking.
What does a young woman who lives off the grid and spends her free time editing Wikipedia entries and picking fights with people online have to do with a circle of intellectuals debating time and space in Vienna on the eve of World War II? Kirsten Menger-Anderson’s beautiful meditation on time, love, and obsession shows us how we never truly know what happened in the past, and often how the past eerily mirrors the future.
