To kill a mockingbird - lee Harper

I picked this book  because I know at one point we will have to read it in English,  and I was generally really interested to see what it was about, I read  the back and and was interested by 'shoot all the blue jays you want, if you can hit'em, but remember its a sin to hit a mockingbird,'

its about a family in the deep south of the 1930's.

update
there are 3 boys Scout and Jem Finch and their friend Dill, all summer they played a game called boo radley witch also is the name of a well known man  in the town of Maycomb, Boo Radley is well known for being the towns crazy scary old man and scout Jem and Dill act out crazy things.
one of the scenes was jem who was acting as boo radley stabbing dill in the leg.
