Tonight on Newsnight and Newsnight Review we are talking about anger.

The next few days will see the start of a series of protests in London in advance of the G20 summit on the global financial crisis. The protesters will be focussing on the popular villains of today, the bankers. And, of course, governments.

But how much anger is there out there more generally? And if we are angry, what are we angry about? And who are we angry with? We want you to tell us what you think.

One newspaper columnist this week said Britain was seething with rage. Is that true?

Are you angry about MP's expenses? Unemployment? Life in general?

Are you in fact - "mad as hell" and unable to take it anymore?

We'll discuss it all on Newsnight.

Plus: the US satirist Stephen Colbert joked the other day that Americans have got so angry they have even started to read books!

One of the books they have turned to is Ayn Rand's seminal novel of 1957, Atlas Shrugged, which imagines a world where the creative, wealthy, entrepreneurial classes (angered by government intervention and taxation) go on strike.

Newsnight Review will be discussing the book tonight, alongside Vince Cable's The Storm, which attempts to make sense of these extraordinary times.

Have you read Atlas Shrugged? If so, tell us why you think people are reading it now.

Has other literature or art helped you make sense of the economic crisis or calm your anger?

We are waiting to hear from you now.
