This is another one of the retellings that add more context to a little known character from myth, in this case, Medusa's sisters. Medusa is also a character included and that haunts the narrative, as we don't get her POV. Unfortunately, the characters feel rathers flat and the book went on longer than the characters could carry it for. The character development was lackluster, and when it did happen, it was rushed (particularly for one character).
