The Imposition of Unnecessary Obstacles
Named a Best Sci-Fi Book of 2024 by Esquire

Investigator Mossa and Scholar Pleiti reunite to solve a new mystery in the follow-up to the cozy space-opera detective mystery The Mimicking of Known Successes, which Hugo Award-winning author Charlie Jane Anders called “an utter triumph.”

Mossa has returned to Valdegeld on a missing person’s case, for which she’ll once again need Pleiti’s insight. Seventeen students and staff members have disappeared from Valdegeld University—yet no one has noticed. The answers to this case may lie on the moon of Io—Mossa’s home—and the history of Jupiter’s original settlements during humanity's exodus from Earth.

But Pleiti’s faith in her life’s work as a scholar of the past has grown precarious, and this new case threatens to further destabilize her dreams for humanity’s future, as well as her own.
