A truly disgusting book that I read because I get a free Kindle selection each month. I chose this one and it was a really bad choice. A horribly disfigured family lives in a locked underground basement--the boy, the brother, the sister, the mother, the father and the baby (None of them are given names). The father is abusive, the sister wears a mask so no one will have to look at her face, the boy collects fireflies. Characters' motivations make no sense and I agree with Amazon readers who labeled the book "sickening." Forget about it.
I love the Iliad, but I didn't care for this retelling that focuses mostly on Achilles and Patroclus. My recommendation: stick to the original.
