This book was so unusual and satisfying in so many ways. Then there was the one bit - if you've read it you'll know which bit I mean - that just knocked me for six and had me in floods of tears. I haven't cried like that over a book for ages. The whole concept of audible thoughts sounds like a nightmare to write, and to read, but it worked very well.
I bought the rest of the trilogy straight after reading this, but this one was by far the best of the three in my opinion.
