I just finished reading Eckhart Tolle's A New Earth and overall I'd say I liked it and recommend it.
While most of the concepts were familiar to me as Buddhist ideas, it was nice to be reminded of them. I did not like his use of his own terminology, though I suppose it makes the concepts less intimidating to non-Buddhists.
To summarize, the book is about letting go of your ego, be aware of your emotional baggage and learn to let go of it, avoid putting "good" or "bad" labels on things, and become enlightened.
Now I'm on to Snow Flower and the Secret Fan by Lisa See! As a Chinese-American, I'm very much looking forward to reading it!
