I'm still in my plague phase, reading the great mortality by John Kelly. Also kind of re reading Patrick O'Brian books and the new bit of the Jeff Somers Avery cates series. I do a lot of re reading.
Probably the relevant bits of Samuel Pepys diaries. The diaries are pretty long but I'm fairly sure you can get abridged versions that cover the plague and the following great fire of London. He was living in London throughout the plague of 1665 and his diaries are a fascinating insight.
