In this touching novel based on real events, Truman "Scrump" Armstrong recalls an idyllic boyhood in 1858 and his family's courage in helping slaves escape to freedom along the Underground Railroad. Then Scrump's older brother, Duff, is accused of murder, and suddenly everything is on the line.

• An innocent child. A nation defined by slavery. A trial that could end a young man's life.

Cass County, Illinois, 1858. Nine-year-old Scrump Armstrong's days are centered around his tight-knit family. But after stumbling across a Black man lynched on their property, the youngster's world changes forever. And as his parents join the Underground Railroad, he fears suspicious neighbors could uncover their dangerous secret. Idolizing his older brother, Scrump is terrified when the nineteen-year-old is suddenly accused of killing their neighbor... a conviction that surely ends in hanging. And his only hope for acquittal rests in the letter his ailing father sends off to a prominent friend, lawyer Abraham Lincoln. Will Scrump's prayers be answered by Honest Abe? More than courtroom drama, The Lincoln Moon is a moving story of family, friendship, and acts of conscience in troublesome times.
