I didn't finish it sadly. I started out about a week ago reading this and found it hard to want to complete. 
 At first, it was difficult to keep track of who was who. Had to make a Google Keep note on which princess was which. Then as the pages wore on I realized that I didn't care much for the story, or the style. It's all written as letters to Rapunzel. Perhaps had the story been written differently I wouldn't have given up so soon. 
 As far as the characters go, the only one I liked was Cinderella (CeCi). She was the only one that was normal, not too naive and sweet like Sleeping Beauty (Rory), or an overbearing know-it-all like Snow White (Bianca). 
 Also, the talk of Pages that needed to be complete made no sense to me. Their story as far as it goes should have already been completed since it was set in our age. But speaking to that, had I been more into fairy tales I might have enjoyed this more. My only knowledge being Disney from when I was kid. 
 I found too the blending of other fairy tales and other alternative realities to be clumsy. Talk of going to Wonderland, or visiting Oz, getting something from the Hansel and Gretel bakery was too much. I get that this is a world of human imagination, it just felt as if it were all mashed into the story for the sake of being cute. It wasn't, it got old. 
 I will say that I skipped all of the middle and read the end. The ending wasn't bad and perhaps in the future I will come back and keep progressing through the story, even though the ending did a nice job summing everything up. 
 This is an honest review for my copy from NetGalley.
