I haven't read a lot of fiction by Latin American writers or writers with a Latin American sensibility, but I've noticed a pattern.  Junot Dias, like the better-known Gabriel Garcia Marquez, crafts stories that are complicated and dense, and they play with reality in ways that are, well, "foreign" to me.  Miracles happen.  Curses (fuku) are cast, and they apparently work.  People have visions and they foretell the future.  The dead return, or at least they visit the living in dreams and visions.
