Sadie is getting ready to host a small party at her house, but she's nervous that her guests won't enjoy it. She decides to use a new organiser app on her phone, called the Toady Booster, to help her plan the party.

Sadie catches Max snooping around her room and throws him out. At school, students at Harmony High are being turned to stone by a strange shadowy figure, and the Wardens accuse Sadie of unleashing dark magic upon the world.

Sadie and Blaine are in the forest, practising levitation spells, when Zaine, Blaine's older (and super cool) first cousin appears. Zaine offers to help Blaine with some risky magic.
