Book excerpt: On a plantation somewhere down south, a mystical tree reaches up toward heaven. Generations of slaves have been hanged on this tree. But James is going to be different, as long as he keeps his head down and practices his reading. Moreover, as the Civil War rages on, the possibility of freedom looms closer than ever. When a stranger arrives on the plantation, a striking romance emerges, inviting the couple and those around them into uncharted territory.
