Super Sneak (Hannah Montana #3) by Laurie McElroy

Red-carpet Caper

When Miley is invited to a sneak preview of a hot new movie, she's sure that her dad won't mind a bit. After all, she's famous. He can't say no, right? Wrong! It's exam time, and Miley's dad wants her to stay home and study. But Miley just can't resist. She sneaks out of the house and off to the movies with Lilly and Oliver. 
Then, when her dad shows up at the same movie theatre, Miley realises that she's not the only one who has a secret. Mr Stewart--who is single--is there on a date with a mystery woman! Who could she be, Miley wonders? And why would her dad hide something from her? Maybe Hannah Montana can help Miley get to the bottom of things!
