This is a retelling of The Iliad - no need to read it however a bit of the basics of it would help you understand this book more, just for background information.
It can be a rather difficult read. Not to say it’s hard to understand, but more of the detailed subject matter. It’s shocking to read when these women are going through an era where war is prevalent, and the best outcome for them is to be a trophy, instead of a slave. (Although, those two terms are pretty much the same thing if you think about it) It’s scary, and eye opening at the same time. These women go through a lot of trauma and Briseis has it slightly better than the other women out there (which says a lot). They’re pretty much treated like cattle and nothing could be done with it. Unfortunately this is the norm during war.
The relationship between Briseis and Achilles was interesting. Despite the conqueror and war trophy titles, it develops and evolves as Achilles goes though life changing events through the novel. You do however, have a heart for Patroclus. He seemed more human and his friendship with Briseis is what might have kept her going through all this time in the book. In a sense too, she also benefited from being with Achilles (albeit, not her choice)
This is definitely word a read through if you’re interested in Greek Mythology and retellings this is worth the read, despite the slow but steady pace. The retelling of the Iliad from Briseis’ point of view is a good one.
