This is more of an alternate universe version of Peter Pan than a prequel.
The plot shows Peter meeting most of the characters we are familiar with but ... Most of the traditional "bad guys" - Captain Hook etc. - are reimagined as good guys. We will need another story to explain how the good guy Hook becomes the bad guy we all know and love to hate. If you are only interested in Pan stories that don't contradict the Cannon as written by J. M. Barry then stay away. If you want a fun story inspired by the idea of Peter Pan but different you might enjoy this.
