Determined to find her lost younger sister, Marianne Neumann takes a job as a placing agent with the Children's Aid Society in 1858 New York. She not only hopes to offer children a better life, but prays she'll be able to discover whether Sophie ended up leaving the city on an orphan train so they can finally be reunited.
Andrew Brady, her fellow agent on her first placing-out trip, is a former schoolteacher who has an easy way with the children, firm but tender and friendly. Underneath his charm and handsome looks, though, seems to linger a grief that won't go away--and a secret from his past that he keeps hidden.
As the two team up, placing orphans in the small railroad towns of Illinois, they find themselves growing ever closer . . . until a shocking tragedy threatens to upend all their work and change one of their lives forever.
