Song Yet Sung by James McBride

This is about slavery before the Civil War. It takes you on an adventure through the swamps of Maryland's Eastern shore. How one runaway slave, Liz, stirred up ideas of freedom in other slaves. Slaves were sometimes stolen and resold for profit. Liz and nine others were held captive in a thief's attic. One old woman tried to teach Liz the "code". The "code" was the language of the slaves on the run. It told them when it was safe to travel and which way to go, how to make a friend, and more. No one gave up the code. They would die first. Once I started reading this I couldn't put it down.
