There is no such a Book. The Bible is whole only when it contains its 66 books. Each book has its value and significance. From Genesis to Revelation the Bible keeps up the same theme.

Taft became the only President to also serve as Chief Justice, and therefore is also the only former President to swear in subsequent Presidents, giving the oath of office to both Calvin Coolidge (in 1925) and Herbert Hoover (in 1929). He still remains the only person to have led both the Executive and Judicial branches of the United States government.
The Bible
Only one Bible book was written by Jude, the one that bears his name.
In the bible there is only one Hannah mentioned , it comes in the book of Samuel.
The book of Obadiah is only one chapter long.
This is news to me, but as far as I know, there is only one book in the Bible that does not have the word God in it. That is the book of Esther.
