first-gen immigrant experience exploration recs?

hi! ive recently read 2 books that lightly touched upon the first gen immigrant experience: Severance (where 1 person was happy to emigrate, the other was not) and The Satanic Verses (where both of the people were sad to emigrate + had to witness their children reject their culture in favor of the British one). Both novels dedicated just a few pages to these issues and left me wanting more. could you recommend me any good books where first gen immigration and the challenges that come with it are explored fully as the main theme?
