Life goes on but classics endure

It has been a very very long time since I wrote on this blog. Life as it tends to do sneaks up and allocates your free time to everything. I certainly want to post more about classics on this blog. I want to share what I have read and hear what you have read and get suggestions. So please feel free to comment on suggestions here on this post. I know that I do not have a very big readership. I thank ETJ for following me so many years ago (he knows who he is). I will hopefully be adding a new blog post soon and try to get into a rhythm publishing a new post.

Iron Heel by Jack London

I was looking at Wikipedia's list of dystopian novels and came across Jack London's "Iron Heel". It looks very intriguing.

Have any readers read this classic? If so please leave a comment telling me what you thought of it. Is it plausible?

What do you recommend?

Hello all,

After an extremely long hiatus from posting, here is a short and sweet new post.

What are YOU reading that is a classic?
What do you consider classics that do not currently have 'Classic' printed somewhere on them? (Such as Signet Classic, Bantam Classic, Perennial Classics, etc).

I have been reading Jim Butcher's series "The Dresden Files" (currently on book 3, Grave Peril).
I do not consider this to be a classic. It is entertaining though!

So let's hear it... what do you consider to be classic AND have you read it this year? Are you reading it right now? How many times have you read it?
