As the stakes grow, Eva takes charge of the operation, forms a deep bond with the children she is protecting, and works alongside Geneviève to rescue Rémy after his arrest by the Nazis. The network's collapse reaches Eva through the ruins of the raided church and a harrowing visit to the local prison, where she learns her mother has already been killed.

Rémy's coded promise that he will return gives Eva hope even as the dangers around them escalate, and their brief reunion at the Swiss border becomes the last tender moment before everything falls apart. When a dying Geneviève names Joseph as the traitor, Eva loses nearly everyone she loves but refuses to let the children's identities be erased along with them. Decades later, a coded dot in a borrowed book keeps alive the impossible hope that Rémy survived, and a stranger's claim on the Book of Lost Names delivers the most unexpected turning point of all.
