Reading Suggestions?

In the past year or so I have started taking a fair bit of interest in both politics and economics, at the moment I would probably identify myself as a classical liberal but I realise there is a lot I don't know so I am looking to inform myself a little. My exams will be over in a couple of weeks and I would like to spend at least some of the summer reading up on economic and political philosophies from across the spectrum. I would really appreciate any suggestions for reading material from anyone on this sub. Thank you!
