The Long Earth: Tremendous Book

Dear Readers, If you are thinking about reading this book, commence the reading! It is really a great book that would interest people of all ages. I'm twelve and I think the wit Sir Terry displays is of great magnitude. I would highly recommend this book to advanced readers who are looking for a well-written book.

The Long Earth

Loved this book but it has a lot of cursing but no sexual themes I won't let my children read it though until they are 18-19 because they say the F,S,H,and D words.
