If anyone has read/heard about the books "The Namesake by Jhumpa Lahiri" and "The Writing on my Forehead by Nafisa Haji", can you please help me come up with a nice comparative thesis?

A topic/theme I have for both is identity. But can't think of good subtopics for that, except for the face that both main characters rebel against their culture and family to find themselves.

Please help?

Lahiri uses motif and characterization to portray gogal ganguli’a change in attitude and quest for his own identity throughout his childhood and early adult years
