I absolutely adored this book!
To start, the college kid who wrote it is as gifted an essayist as any you can imagine. His prose just is wonderful to read, and draws you into his head; the style seems effortless.
The book itself is a fantastic cross between an immersion-ethnography, in which a researcher joins a society, and makes informant contacts, and a humorous travelogue. In fact, to this boy, Liberty U might as well have been on the other side of the world.
Roose writes with compassion and a wide, wide open mind. He reveals himself to be a wonderfully curious person, and spares himself nothing. Like all travelers, he makes faux pas, suffers embarrassing incidents and otherwise falls (mostly gently) over his own two feet, as only a young person can.
I'd recommend this book to just about anybody of any religious persuasion. If you are mightily religious, it will give you a perspective on yourself. If you are closer to the atheist end of the scale it will provide a peek into evangelical thought.
Mostly though, this was just plain fun to read.
