I hesitated before starting The Secret History because it is by the same author as The Goldfinch. I read The Goldfinch under the heaviness and craziness of jet lag and so I wasn't sure if it was the book or the jet lag, but I felt pretty punchy.
I read The Secret History anyway, and it is some heavy duty reading. It's the tale of a group of college students at a small liberal arts college who are in on a secret. Keeping this secret tears them all apart physically and emotionally in different ways. Psychologically insightful and deftly written, I would recommend this if you're looking for a solid book to read, but I actually did like The Goldfinch better. Make no bones about it...this is not lighthearted beach reading fare.
