Alexie's autobigraphical character in Part-Time Indian struggles moving from one culture into another and finding that acceptance or belonging to which you have referred. Pip in Great Expectations too works to move from one culture to another socioeconomically.

If you are organizing a literary analysis paper that compares this theme, you might pick three ways the authors both do that in these two works: characterization (which shows the change in each over time), plot development (focus on the complications in the rising action of both... it makes the reader feel compassion for the unaccepted character), and setting (living conditions for characters as they strive for belonging).  

Great Expectations is a tough read and would impress your teacher. But, for time's sake another text to consider is Speak by Leslie Halse Anderson. It is more contemporary work and a quick read.
