This wasn't really so much a sequel as it's a second story that clarify who Jack is. Which is fine and fun but not really continuing Punzel's journey. 
 Overall I enjoyed this, it wasn't anywhere as fun as the first book, but it had it's moments. It seemed to go by quicker. Maybe because the first one encompassed so much while this was just Jack's story. 
 I still don't like Jack, not a huge fan of him even if they explained why he does what he does. The drawings are fun, and very colorful. I wonder if there will be more to these stories I'd read them!
