Unwilling to be separated from Mal, Alina hatches a plan to join him on a perilous expedition through the Fold. Kaz chases a lead on a lucrative job.

Alina's actions against the Volcra bring her to the attention of General Kirigan. Kaz runs into trouble while looking for safe passage across the Fold.

Ensconced in the lap of luxury among the Grisha, Alina begins her training. The Crows — Kaz, Inej and Jesper — prepare for their risky journey.

As Kirigan takes Alina into his confidence, Mal volunteers for a dangerous tracking mission, and the Crows plot a heist to get into the Little Palace.
