As a queer native woman, I really hoped to love this one. Some of the ideas in here were really interesting, but the book just felt so disjointed. And I had no one to root for: Steph was just so selfish and self-absorbed and reckless and stubborn! And she never grows as a character or learns anything. And her sister Kayla and her mother are self-absorbed too, though in slightly different ways. Parts of their stories were interesting, but didn't really fit with Steph's story. The author was just trying to explore too many topics.
I also don't like how the character Della was used as a plot device - especially since she completely disappeared halfway through after being a POV character (well she had a minor appearance later but basically disappeared). It should have been a book about Della or she shouldn't have been included at all.
The blurb also made it sound like there'd be a lot more space, but it was a lot of her childhood and college life. At the same time, we skipped over years of her life that I would have been interested in - like her learning she got into NASA, which was her main drive.
