Its party time for Hanna’s better half: Mona Vanderwaal! The other maarufu girl of Rosewood High (after Hanna and Alison of course) is having her birthday bash in the woods. It’s a glamping trip: like camping only with glamourous tents housing massage tables, spa treatments and make-overs. Everyone who’s anyone in Rosewood is invited…except for Hanna Marin.
