Michael H. Cottman’s Shackles from the Deep is a literary non-fiction about the history of trans-atlantic slave trade and slave ships. This book is about the author re-tracing the path of a sunken slave-ship named the Henrietta Marie, and visiting the various places of history where the slave ship docked and traded Africans, just for the author to raise awareness of the slave trade. Through his expeditions, the author learned of the immense cruelty the enslaved faced, and how they recieved discrimination even after their liberation.
