maybe you've already read some of these but...
for fiction I would suggest:
Never Let Me Go - Kazuo Ishiguro
A really beautifully written story about a boarding school romance that runs it's course over the life of the characters. It's got a really gothic color to the story, and it's really good.
The Curious Incident of the Dog in the Night-time - Mark Haddon
This one was a fun story because it happens from the perspective of an autistic boy. It's a mystery that is assembled in a unique way by this boy.
The Brief Wondrous Life of Oscar Wao - Junot diaz
I'm reading this now. There are all kinds of Dominican Republic cultural references, and pop culture references from the 80's but it's super good, and the language is really effective and fun.
The Omnivore's Dilemma - Michael Pollan
This book was really fun to read because it explained a lot about the food that we eat in our society and where it comes from. The author decided to write a natural history of 4 meals a fast food meal, an industrial organic meal, an organic meal, and a hunted and gathered meal. and traces all the ingredients back to the farms, forests and places he found them.
The Devil in the White City - Eric Larson
This is a social history about the 2nd Chicago World's Fair at the turn of the last century. It's cool to read about ideas that really are part of our lives today that were first invented at the turn of the century. Ideas like urban planning, living in the city, electricity, steel and glass, and serial killers. It's cool that the book reads like a mystery novel because it tracks the life of one of America's first serial killers as it explains all the different social change that was changing American life to the kind of modern life we live today.
... and Wuthering Heights is awesome too.
