Twelve-year-old Tess loves fashion, but she has a soft spot for accessories. In fact, Tess runs her own consulting firm for the kids at her school. If you need the finishing touch for middle school dances, special occasions like a thirteenth birthday or bat/bar mitzvah, Tess can make it happen. She loves reading The Miscellaneous Moxie, THE online fashion blog that's as crazy about accessories as Tess is.

So when the blog opens up a contest, calling all of their faithful readers to enter to win a chance at designing an accessory of their very own, Tess jumps at the chance to create something that will wow the judges.

But things get more complicated when her former BFF turned frenemy, Kayte (who added the y to be "unique"), a self-proclaimed fashion plate, tries to encroach on Tess's turf--and submits her own entries for the blog contest. In the midst of the Bling War, Tess discovers that a precious locket from her beloved grandmother, Mimi, is missing. Can Tess solve the mystery behind the missing necklace and get crowned the Bling Queen, too?
