Meet four best friends. They're not super…yet. IRIS:Visionary, artist, leader--the glitter-glue that holds the group together. CHERI: A girly-girl on platform roller-skates who's never met a rescue puppy she didn't immediately-and-madly love. SCARLET:Short enough that you won't see her sneaking up behind you. Freckled enough that you might mistake her for innocent. But look out! She can pants a bully faster than you can say O-M-Jeepers! OPALINE:Loveable, huggable, supershy, sweet as pie… or is she? And introducing CANDACE. Not just any babysitter-she's a Teen Genius, thankyouverymuch! What happens when four best friends find themselves splattered with mysterious purple goo during a routine sleepover? Iris, Cheri, Scarlet and Opaline are about to become… THE ULTRA-VIOLETS!
