This is a young adult book based on a young adult TV series on TNT. It chronicles the adventures of the Librarians. These are not your stereotypical schoolmarm type librarians. This group of adventures are charged with gathering magical and mythical books, artifacts and treasures that may be too dangerous to be in the public purvey.
This specific adventure focuses on Mother Goose tales and the dangers inherent in rhyming. There is very mild violence and lots of references to magical and mythical things.
The story line and plot are clearly meant for the younger reader.
It seems suitable for 4th or 5th graders.

This book may have been received free of charge from a publisher or a publicist. That will NEVER have a bearing on my recommendations.
