School for Spirits: Almost an Archangel - Spirit School, #6

Ever since she's been dead, Kaylene's had one dream: to become an Archangel. Her training has been her focus, her obsession, her passion-and now she's only five missions away from making the dream come true. Kaylene's dedication has made her one of the most popular Archangel candidates. She has a legion of fans and a portfolio of glamorous pictures. Every magazine wants to interview her, every spirit wants to be her, and no demon can withstand her blade.
Kaylene can handle anything that comes her way, but she'll face her biggest challenge yet: a rebel student named Ben. Almost an Archangel is the sixth book in the Spirit School series.
