Unconquerable Sun

The idea/premise seemed good (Female Alexander the Great in Space!) but I think the execution lacked focus. There were 2 major points of view: Sun was third person and Persephone was first person. Each chapter had a different POV and sometimes I had a hard time discerning which character was talking. Although Sun was the main character, Persephone (in the first-person narrative) was way more interesting. The book felt a bit longer than it should be and the amount of world-building info dump bothered me at times. I was not excited to continue reading the series.??
