No, but interested to hear your thoughts and pleased they're positive! I read Heartbreaking Work of a Staggering Genius when I was about 20 then immediately read it again, I loved it so much. Read couple of others and rates them but didn't affect me so much.
Might have to put new one one my Christmas list (for DH so then I can read it 'for free')
It's the best book I've read in a long time- like you, I loved A Heartbreaking Work of Staggering Genius, probanly one of the few books I have re-read several times. I quite liked You Shall Know Our Velocity but haven't been inspired to read any of his others. The Circle is great though, very addictive. It's a bit 1984, about a girl who starts work at a place called The Circle which is an all-powerful technology company, kind of like Google/Facebook/Twitter/Amazon all rolled into one. It's scarily realistic and very well done.
