The Book Jumper is the story of Amy Lennox who moves from Germany to Stormsay in Scotland to go to her mother's childhood home: the Lennox House. Upon arrival Amy realizes her mother's family has a strange ability to jump into stories and interact with the characters and protect the stories from anything that tries to alter the writing. They are called Book Jumpers. When Amy realizes that she is one too she explores the book world with Will who she met on the island. Together they find that there is a book thief in the stories who is altering them and stealing the book's ideas and possibly could be after their lives.
The Book Jumper is a pretty good book overall. In parts it can be predictable but others have more suspense. I would recommend this book to any fantasy reader.
