TMI is the go-to app at Petraka Academy for anyone looking to navigate the rumor mill. Because if it's on TMI, then it's real. And no one swears by it more religiously than queen bee Rosie Geld. Adrienne has always been a people watcher, and the launch of TMI gives her the chance to put her skill to good use. But as inconsequential rumors either pass or fail the TMI test, her goal becomes much bigger. She knows something. Something no one will believe. She knows that Rosie Geld killed Audrey Hart. And the moment it will hit TMI, everyone will know it's real. Everyone will know who was involved. And everyone will pay.
