I don't usually read Peter Pan retellings because I love the original one so much. 
 A boy who represents childhood, who can never grow up by learning from experience as we all do and copes with the fact by forgetting past adventures and having nightmares at night. Captain Hook representing the older generations, always fighting the young ones and always losing to them... I love the story and I always fear retellings will ruin it. 
 However, I had heard great things about this book and kind of wanted to go back to Neverland for a while, so I gave it a chance. Maybe I had very high expectations and that was the problem, but I was disappointed. 
 Don't get me wrong, the story is original; Pan being not as good and Hook being not as bad, the reason why Gwen is taken to Neverland, and the story behind the current events... that was not the problem. The plot was interesting and very fast paced, full of adventures and magic. 
 The problem was the characters. 
 Gwen is annoyingly stubborn, but, that wasn't the problem either. The main reason I didn't love the book lies within the secondary characters. Fiona, the Queen, Rowan, Olivia, Pan, Will. They aren't entirely cardboard, it just felt that the book needed a few extra pages so we could get to know them better and care. A lot of attention was put into Gwen, but every other character felt unpolished, even (view spoiler)[ Rowan, though we learn a bit of his past through this paragraphs before each chapter (which I really liked) (hide spoiler)] felt under developed. Maybe a multiple POV would have helped. 
 Besides, the ending felt a bit rushed... maybe I didn't get it... (view spoiler)[ What really happened to Neverland without a queen? Did it crumble? Did everyone die? Isn't it a bit selfish of Gwen to abandon Neverland knowing she is its only hope? And why did they help her go back if she wasn't helping them? (hide spoiler)] 
 Sorry, but I didn't buy it. The book needs a sequel, prequel or 100 more pages to further continue the development of the characters and the world building.
