It took me almost 50% of the book for me to really get into it. The family dysfunction was annoying at first, but as the Shao sisters are forced to work together to figure out what‘s going on with their brother, the story really picks up. The sci-fi elements are both central to the story but also not. I already recc‘d this to someone looking for a space opera. Takes place on Earth, but has that genre‘s mix of epic action and personal drama.
