Seven-Day Escape

Serena Shaw and her colleagues are trapped in the Mistwood Sanatorium, in a seven-day loop. To survive, they must complete prompts each day, as those who fail vanish. A Silver Vein appears on her wrist. She meets Caden Quinn. They team up, discovering The Loop is a glitch in a Fragment's rules, and the Silver Vein is a Resonance Brand. They shatter The Loop, only to be thrown into other Fragments. Thus begins their escape across multiple realms, searching for a way back home.
