I enjoyed the book a lot, but I can't help but feel like it's more because of my love for the source material than anything else.
I really, really wanted this to coincide with canon, but as the story progressed I realized it didn't. I noticed some parallels between this book and the original Rapunzel tale, though, which was pretty interesting.
My biggest gripe is in the final couple of chapters. The final chapters take place during the movie, so it stands as mostly a recap. A few characters secretly watching the events of the movie and commentating. It just hadn't felt necessary and I felt like could've been handled better.
But my original statement stands. I LOVED reading the book. It was fun and I've recommended it to lots of people, despite my gripes. The second I bought the book, I couldn't put it down.

The plot was slow and I wasn’t interested in the characters or the story.

I love this series! I think this one could have been a little shorter but I still really enjoyed it.

I thought this was the most interesting of the series. It added some fun twists and is a little known character.
