Let me just say one thing. This is one of the best series I have ever read. After I finished Pendragon, ( Which is also an AMAZING series ) I had to read his other books. This one in particular was very detailed. I love how they tie in some things from Pendragon, like that Solara is where the souls go after the Black, and that the Watchers are the Travelers from Pendragon. I don't want to say anything that happens in this book because that will give it away, but some pretty surprising things happen in it! I really recommend this series if you haven't read it. D.J. MacHale is a truly amazing author. If you want to check out some of his other books, you really should read Pendragon. Pendragon is about a kid named Bobby Pendragon who discovers that he's a Traveler. And I like Pendragon because it jumps right to the plot. Some books are boring, and FINALLY after you read half of the book you reach the good part. Pendragon ( And Morpheus Road ) aren't like that. Morpheus Road is extremely exciting and you'll never be able to put it down. After I read the first sentence, I was hooked. Most books that I've read I usually take a little break and then continue reading, because sometimes it's a little boring. But Morpheus Road is exactly the OPPOSITE of boring! I never took a break. I don't think this book is that bad for younger children. Maybe it is. I'm not completely sure. I think 9 or 10 is the youngest, but who knows. I started reading Pendragon when I was 9, so I guess it's fine if you read Morpheus Road when you're like 10. There's not that much bad language in it, but it's pretty complex and might be a little hard to follow along. That's why you have to pay close attention to the little details. Like those golden orbs, you find out in about the 2nd book that they're a lot more important than they seem. And by this book, there's barely any of them left. This book ( In my opinion ) is the best in the whole series. There's so much in it. When I finished it I was breathless. I hope this review makes you read this series ( Or book if you've already read books 1 and 2 ) because all books written by D.J. MacHale are the best.
