The Adventures of Huckleberry Finn by Mark Twain
Set in the racially-charged American South of the nineteenth century, Mark Twain writes of youthful adventure and unlikely friendship across social divides. Both on the run, Huck and runaway Slave Jim journey down the Mississippi River together in search of a fresh start- but of course, nothing is that simple!
