Investigator Mossa and Scholar Pleiti reunite to solve a brand-new mystery in the follow-up to the fan-favorite cozy space opera detective mystery The Mimicking of Known Successes that 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 could be found in the outer reaches of the Jovian system-Mossa's home-and the history of Jupiter's original settlements. But Pleiti's faith in her life's work as 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.
