The Haunted Stepsister — Medeia Sharif

Sixth grade isn't easy for Jesenya Moradi, especially since her mom's recent remarriage and tension with her new stepsister, Kammy. After an incident at school that nearly destroyed Kammy's life, Jess has been desperate to get on Kammy's good side. But a fateful trip to an allegedly haunted bathroom changes both girls' lives forever.

The rumors about the bathroom are true, and now Jess is convinced a demon's possessing Kammy. Eerie things happen whenever she's around - flying objects, flickering lights, not to mention the fact that something, or someone, is making people into its puppets.

Worse, the demon seems fixated on making Jess confess her part in ruining Kammy's reputation. Sticking to her Muslim faith, Jess enlists the help of an imam to exorcise the demon from Kammy. But can they get rid of the demon before it destroys her new family?
