Are you a Belieber? Justin Bieber's meteoric rise from a regular kid in small-town Canada to -the most famous teenager on the planet- has captivated the imagination of a generation of young devotees known as -Beliebers.- With record-setting album sales, more than 11 million followers on Twitter and the highest-grossing concert film of all time, the 17-year-old pop star has legions of fans around the globe who hang on his every word.

Could a powerful spiritual yearning be lurking behind all the purple and puppy-love lyrics? With the keen eye of a veteran religion journalist and culture watcher, Cathleen Falsani takes an in-depth look at how the bold yet humble faith of this teenage uber-celebrity is not only a key to his staggering popularity, but an influence that is shaping the lives and hearts of young people (and more than a few of their parents) worldwide.
