I recommend Skellig for 10-14 years old boys and girls. If you like mysteries and like to be left hanging, this is definitely a book to read! I liked this book because of the weird things that happened. There are some things that leave you wondering. At one point in the book the old man says, "27 and 53" and you might think it doesn't have to do with anything, but it appears throughout the whole book. Mike's friend says to him, "What's wrong with you?" That leaves you hanging because by this point you're so into the book, you want to know what happened. Even though it's not one of those really important parts but it's a mystery that the author throws in to keep you wondering. But in the end you finally find the answer to all the mystery's and the problems. That was why I liked this book because at first I was confused but in the end it all came together.
