I really liked the premise of the story. Children coming back from their fantasy world like Alice coming back from Wonderland? Sounds interesting. But this story isn't so much about how these children go on with life as figuring out a mistery. I didn't mind that much since it was still an interesting story but the ending was really lackluster and left me unsatisfied. I will pick up the next one though since the idea behind this story was really cool and you fly through them anyway. I hope it tells me more about the special worlds or the kids themselves.
