Just finished this book. It won the Pulitzer Prize in fiction for 2008.
The novel is an epic love story narrated by Yunior de Las Casas, the protagonist of Díaz's first book "Drown" and chronicles not just the "brief wondrous life of Oscar Wao," an overweight Dominican boy growing up in Paterson, New Jersey and obsessed with science fiction and fantasy novels, with comic books and role-playing games and with falling in love, but also the curse of the "fukú" that has plagued Oscar's family for generations and the Caribbean (and perhaps the entire world) since colonization and slavery.
I highly, highly recommend it.
