A Whole New Plan Book Cover shown in paperback, tablet, and phone for e-book versions

A wounded Pinkerton agent. A cautious pastor. When danger threatens, only faith—and God’s perfect plan—can show them the way forward.

Sometimes God’s best plan is the one we never expected.

California, 1870. Pastor William Baker built his life on steady faith and safe choices, but the arrival of Lydia Spencer upends everything. Independent, outspoken, and hiding a limp from a recent injury, Lydia is unlike any woman he’s ever known. And she has no interest in church—or in sharing her secrets.

What Will doesn’t realize is that Lydia is a Pinkerton detective, undercover as a schoolteacher while tracking a dangerous crime boss. She’s determined to protect her friends in Washton… even if it means keeping her distance from the kind, steadfast pastor who sees too much.

When strange thefts strike the ranch and a frightened boy appears with ties to their past, Will and Lydia are thrown together in a search for truth—and find themselves fighting not only for justice, but for a future neither had planned.

Full of faith, mystery, and romance, A Whole New Plan weaves a story of healing hearts and unexpected love that can only by written by God’s perfect design.
