To Kill a Mockingbird

Harper Lee's To Kill a Mockingbird contains two parallel plots that only converge near the end:

The first plot revolves around Arthur "Boo" Radley, who lives in a shuttered house down the street from the Finches and is rumored to be some kind of monster. Scout, Jem, and their next-door neighbor Dill engage in pranks, trying to make Boo show himself. Unexpectedly, Boo reciprocates their interest with a series of small gifts, until he ultimately steps off his porch and into their lives when they need him most.

The second story concerns Scout and Jem's father, the attorney Atticus Finch. The local judge appoints him to defend a black man, Tom Robinson, who is falsely accused of raping a white woman. Atticus suspects he will lose the case, but he faces up to the challenge just the same, at one point heroically stepping between his client and a lynch mob.

Along with its twin plot lines, To Kill a Mockingbird has two broad themes: tolerance and justice.
