The Imposition of Unnecessary Obstacles (Investigations of Mossa and Pleiti #2) by Malka Older

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. Hardcover; 224 pages
