When the Public Library is Outside Your Bedroom Window

One could ask why doesn't Z take the initiative to choose a book for himself.

Why didn't he discover
He could go to the school library. Doesn't Z live so close to a public library he can see it out his bedroom window? 

Yes, you would be correct., but for some reason the adolescents I know never seem to want to just walk right down the street (or hall for that matter) and look through a bunch of books.

They want recommendations from friends, teachers, parents, probably in that order.

Take a look at Chicago Public Library: Books for Teens to give you ideas about books you should read and then recommend.
