Twelve-year old Rose has an issue. A big one. She turns invisible randomly, unable to speak or be heard or do most normal activities until she reappears, also randomly. Her parents decide to send her to TOCS, a class that will fix her problem. But what is in store for Rose at TOCS is beyond what she ever dreamed. She'll fight villains, rescue heroes, and maybe, just maybe, if she's lucky, she'll become a hero herself.
