This book is the fourth in a series about (you guessed it!) Peter Pan. It's mostly a prequel type thing, explaining how Peter came to live in Neverland and why he never grows up and such. In the books, he and a group call the Starcatchers seek to protect starstuff, which falls from the sky and is immensely powerful, from the Others, who would use it for ill. In the third book, they thought they had defeated the Others for good, but now it would appear that their shadowy leader, Ombra, has returned and is controlling the King of England in order to try and get at the starstuff once again and take over the world and such. Molly and George Darling, along with many of the other former Starcatchers, have been captured, so it is up to young Wendy to bring Peter back to London and enlist his help in saving the day.
It's been awhile since I read the first three books, so I was a little confused at the beginning- characters, events, and places that should have been familiar weren't. But my memory eventually jogged enough to understand what was going on and enjoy the book. I love stories about Peter Pan, despite the underlying sadness that Peter will never be able to grow up. So that's 22 down! Hopefully I can make some better progress over break :)
