Tuesdays at the Castle is about a royal family that lives at a castle which renovates itself every Tuesday. When the King and Queen go missing while picking up the eldest brother from college, the three younger heartbroken children try to track down their parents and older brother. I liked this book because of the suspense. I would recommend it to kids who like castles and stories about different times. I think that kids from ages 8-12 would really enjoy this book.
