This feels from the beginning very Creative Writing-ish, with people like our first narrator, Pauline, talking about morning light shimmering and an "apricot horizon." So, at the very least, it makes me feel like the character is quite sentimental.
We have four characters as narrator, Pauline, Maggie, Willa, and Evelyn, so that strikes me as a guaranteed recipe for confusion. You'll have to keep track of them all.
The description on the dustjacket makes it sounds like the characters are recent immigrants, but I don't think that's the case. Their grandmother came from Germany and went to someplace called "Quakertown" and that's not just a nickname for Philadelphia because it's clearly mentioned as someplace else? It's hard to follow. There's a lot that's just not explained and might not be accessible to the reader.
Probably this is best as a book giving a certain sense of place and time--Philadelphia in the 1910s.
Given the writing style, if you like a book like "To Kill a Mockingbird," you'll probably like this.
