Maybe the book contains powerful spells for Celestial Spirit Wizards, and in the Grand Magic Games something like this might happen:

Lucy on the ground all beaten up before one of the main antagonists and Levy come running from behind. Lucy reads through it and closes her eyes. Suddenly, gravity is nullified and the sky turns dark. Planets start appearing everywhere while Lucy chants a spell.  Measure the heavens, and open them wide...'' Through the shining of all the stars of heaven, Make thyself known unto me  ''O Tetrabiblos...  I am one with dominion over the stars...'' Release thy aspect, a malevolent gate  ''O eighty-eight signs...  Shine!'' Urano Metria!
 * Levy: Lucy-chan, Lucy-chan!
 * Lucy: Levy-chan...
 * Levy: Hold on Lucy-chan. I've read this book I got from the Celestial Spirit world and it contains information on how to cast a powerful spell for Celestial Spirit Mages only.
 * Lucy: Really, Levy-chan?
 * Levy: Yes! However, it requires that the spirits agree to form a contract with you when you cast the spell.
 * Lucy: Don't worry. I have faith in my spirits. They have never let me down and they never will. I love them!
 * Levy: Ok, here use these Gale-Force Reading Glasses to learn it quick.

Yeah, i wish this happens
