Just in time for July.

'Amazing Grace: William Wilberforce and The Heroic Campaign to End Slavery' by Eric Metaxas.

A quite inspiring biography that shows the struggle that Wilberforce endured to help end the slave trade in England 1807, more then 50 years before Lincoln's emancipation. Metaxas also points to Wilberforce's Christian Faith as being the main motivator to abolish slavery. The 'Chaplem Circle' is given a couple of chapters and only a couple of pages actually describes what was involved in the trade which was enough for me. The infamous, 'Zong' tragedy is mentioned as well. An excellent read.
