This whole book feels like a dream, even beyond the actual dream sequences. It starts off with a child's nightmare: being abandoned by the side of the road and forgotten by your family. Then, it turns into a child's fantasy: being important and really good at something that requires little effort, surrounded by loving adults, in a fantastical location that takes cues from real-life buildings.
Although I don't really like surreal types of books, this one is enjoyable. The graphic novel aspects of it are contrasted with the text, and we get a look at what both sisters are doing over the course of the novel. I enjoyed the way the book allows you to piece together what's going on through the mostly wordless scenes of Honey's experiences, and tie them in with Hope's.
I do think a little more attention could have been paid at the end, with a little more information about the world, and why the Memory Bank exists, but that's just my natural curiosity.
