In early 1900s Kansas, Mercy McClain, determined to protect Teaville's children from the bullying she experienced as a child, finds fulfillment working at the local orphanage and serving on the school board. When Aaron Firebrook, the classmate who bothered her more than any other, petitions the board for a teaching position, she's dead set against him getting the job.
Aaron knows he deserves every bit of Mercy's mistrust, but he's returned to his hometown a changed man and is seeking to earn forgiveness of those he wronged. He doesn't expect Mercy to like him, but surely he can prove he now has the best interests of the children at heart.
Will resentment and old wounds hold them back, or can Mercy and Aaron put the past behind them in time to face the unexpected threats to everything they're working for?
