Waves of Mercy Books in Order

The Waves of Mercy books are a two-part historical saga about identity, family roots, and the kind of grace that meets people where they really are. Lynn Austin tells the story through layered timelines, moving between late-1800s Chicago society and the lakeshore communities of western Michigan, where immigrant history is still close to the surface.

In Waves of Mercy, Anna Nicholson seems to have everything a young woman is “supposed” to want—security, social standing, and a future planned out in advance. Then she learns a truth that upends her sense of self: she was adopted. The discovery doesn’t just raise one question; it raises dozens. Her search pulls her out of Chicago’s carefully managed world and toward Holland, Michigan, where the closer she gets to answers, the more pressure she feels from people who’d rather leave the past untouched. Even her engagement starts to feel less like a promise and more like a problem she has to solve.

Running alongside Anna’s story is an earlier timeline following Geesje, a young woman who leaves the Netherlands and comes to America under real strain, including religious pressure and social hostility. Her chapters show the cost of starting over: learning a new land, surviving loss, and building a life when you’re not sure you’ll ever feel safe again. Austin uses these parallel lives to show how one generation’s hidden pain can become another generation’s unanswered question.

At its core, it’s about belonging.

Legacy of Mercy continues Anna’s story as she moves into a new stage of life, still carrying questions that don’t neatly resolve once a mystery is “solved.” What she learns about her origins reshapes how she sees love, family loyalty, and the people she once understood only from a distance. The past keeps tugging at the present, and mercy has to become something more than a nice idea.

These novels are emotionally rich but grounded. Expect social class tension, family secrets, and moments of travel and discovery, alongside quieter scenes where characters confront resentment, pride, and fear. There’s also a gentle thread of romance, but it never erases the harder questions. Austin also makes the setting matter—the pull of Lake Michigan, the rhythms of small-town life, and the contrast with fast-moving city expectations.

Read the two books in order, starting with Waves of Mercy and continuing to Legacy of Mercy. Together they form one long conversation about who gets to define a person’s story—and what it looks like to choose grace anyway.
