Roxie has the best night of her life until the popular kids decide they want to celebrate her birthday in a way Roxie never expects––in her attic, with a gift that’s out of this world, and a pact to never tell a living soul what happens next. Roxie astral projects to Planet Popular where she becomes seventeen instantly and gets everything she’s always wanted, but nothing is as it seems.
