Mara Voss arrives in Vilnius on a linguistics fellowship, chasing a manuscript connected to her grandmother's buried past. Within three weeks, her sponsor is found dead in the university archive at night, slumped over materials he had no reason to be accessing.
The official conclusion: natural causes.
Mara doesn't believe it.
As she works through the restricted cases of a Cold War-era archive, she uncovers a network of suppressed documents, institutional silence, and a corridor that has been hidden inside the university walls for sixty years. The deeper she digs, the clearer it becomes that the people managing the archive's secrets are the same people who invited her in - and that the manuscript she came to find is connected to something far more dangerous than forgotten language.
The Sleepers of Vilnius is a literary mystery set in the archives and courtyards of one of Europe's oldest universities - a novel about what institutions bury, who carries the weight of keeping it buried, and what happens when someone finally starts reading what was never meant to be read.
