This had great reviews but I really struggled to get into it and in the end gave up rather than give any more of my life to it. Hope the next reader has more luck.

blurb-
A ghetto nerd living with his Dominican family in New Jersey, Oscar's sweet but disastrously overweight. He dreams of becoming the next J. R. R. Tolkien and he keeps falling hopelessly in love. With dazzling energy and insight Díaz 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.

Good luck.
