The steamy, sweltering banks of Florida's Ocklawaha River don't look much like Glory Land to young Eve Stewart, despite her father's proclamation. But it's here that Eve, her three siblings, and their parents will settle in July, 1875. Within a few years, Eve's father, Hap, has made good on his assurances. They have a large, weathered clapboard house and a comfortable life, thanks to Hap's job on a steamboat. Eve and her twin sister, Ivy, are blossoming into young women. Yet as Ivy grows more involved in medicine making under the tutelage of a neighboring black woman, her path leads away from the family.

Eve, an aspiring writer, loves her home though she longs to see the wider world beyond its swamps and shores. But when she discovers a secret Ivy's been keeping, Eve must decide between protecting the family name or saving her sister. With the help of a half-Creek Indian tracker, Max Harjo, Eve sets out to find Ivy, beginning a journey that will dare her to follow her ambitions and her passion wherever they lead.
