While the premise was really unique, I think this book felt very uneven. There are two POVs--Hannah (which is 1st-person) and Leah (which is 3rd-person)--and this is where the bulk of that unevenness lies. Hannah's POV was very much magical realism-esque. I think this is where the book was strongest, in my opinion. Hannah's world is much like her sister's, but while she can't interact so much with the people, the world is constantly shifting and bending around her. Especially once she learns a bit more about it and how to manipulate it. I think the commentary, too, on the lies we tell ourselves as well as the ones that the greater world tells us, was interesting. However, Leah's POV was where I really struggled. Hers felt more contemporary in feeling. The timelines skipped around with no real rhyme or reason and Leah, ultimately, wasn't as interesting a character to follow around. I honestly would've preferred if Leah's POV wasn't there. Because here's the thing: her POV didn't really seem to matter.
From both the cover and the synopsis, I expected a mystery/thriller-type story with a heavy emphasis on the sister relationship at its heart, but I didn't really get that at all. This is for one key reason, but it's a spoiler, so I'm not going to say anything. In the end, though, it felt like the relationship between Hannah and Leah didn't ultimately matter, which made Leah's POV kind of pointless.
This felt pretty experimental, but while the central premise was interesting, it didn't work for me. What was advertised in the synopsis--"a haunting novel about sisterhood and grief, where difficult truths must contend with the corrosive power of unchecked lies"--only really hit on some of those points and even then not really in a satisfying way. Honestly, disappointing and not something I'll go back to.
