This is a wonderful young adult novel and series. The vintage photographs are amazing and the way they are worked into the story is fantastic - though Riggs gets better at this as the novel goes on. The first few pictures have a very obvious indication in the text that you are supposed to look for the picture and it's not always on the facing page. This doesn't work as well for an audiobook, because you will want to look at the pictures as you read along.
16-year-old Jacob lead a normal, ordinary life. His family is moderately wealthy. He is taken care of, though a bit neglected - but he doesn't have a closest under the stairs for a room or anything like that. Then he gets a phone call to check on his grandfather, and finds his grandfather on the verge of death in the woods behind his home. Jacob is the only one to hear his grandfather's cryptic last words and decides to try to find the magical island and the children's home his grandfather had always told him stories about.
The book is a little different from the movie. Emma and Olive trade powers for the movie, but Jacob is still attracted to Emma. The ending of the movie is so different from the book, that I get the feeling that the director stopped reading halfway through and just created his own ending. Both the book and movie are very good, but they should not necessarily be compared to each other.
