Things have never been easy for Oscar. A ghetto nerd living with his Dominican family in New Jersey, he's sweet but disastrously overweight. He dreams of becoming the next J R R Tolkien and he keeps falling hopelessly in love. Poor Oscar may never get what he wants, thanks to the Fuku - the curse that has haunted his family for generations. With dazzling energy and insight Diaz immerses us in the tumultuous lives of Oscar; his runaway sister Lola; their beautiful mother Belicia; and in the family's uproarious journey from the Dominican Republic to the US and back.
