Some doors were never meant to stay closed. Sam Hill knows the Big Thicket like the back of his hand. As an ethnobotany student at Sam Houston State, he's mapped its trails, cataloged its plants, and found peace in its ancient oaks. But when a violent storm topples a centuries-old tree, Sam discovers something impossible buried in its roots: an amber artifact, acorn-shaped and pulsing with faint light.
When the artifact activates, Sam is thrown fourteen thousand years into the past---to a Texas of mammoths, saber-toothed cats, and Paleo-Indian hunters who watch him with wary eyes. Stranded in the Pleistocene with only his wits and survival training, he must earn the trust of people whose descendants will leave marks on history at sites like Gault. But every crossing leaves echoes. Artifacts begin appearing in the archaeological record---impossible objects that bear Sam's bootprint, his influence, his presence.
As the modern world closes in and the artifact's power fades, Sam must protect those he loves across millennia while racing against time itself. When someone he cares about vanishes into the ancient past, Sam faces an impossible choice: risk everything on a dying artifact, or abandon them to a world that wants to eat them alive. The SEEDS OF TIME AND MEMORY is a time-travel adventure that blends authentic Texas archaeology with Ice Age survival, asking what we owe to the past---and what the past might owe to us.
