Members of Hanger's Horsemen, Mark Wallace and Jonah Brooks arrive in Llano County, Texas, to deliver a steed, never expecting they'd deliver a baby as well. Left with an infant to care for, they head to a nearby foundling home, where Mark encounters the woman he'd nearly married a decade ago.
After failing at love, Katherine Palmer dedicated her life to caring for children, teaming up with Eliza Southerland to start Harmony House. From mixed ancestry, illegitimate, and female, Eliza understands the pain of not fitting society's mold. Yet those are the very attributes that lead her to minister to outcast children. The taciturn Jonah intrigues her with his courage and kindness, but there are secrets behind his eyes—ghosts from wars past and others still being waged.
However, when a handful of urchin children from the area go missing, a pair of Horsemen are exactly what the women need. Working together to find the children, will these two couples find love as well?
