The Girl Marauder(Book One)

Days are getting darker, the world is falling apart, and Luna Swift is running out of options. She's been on the run for months, hiding from family and the Ministry alike. With nowhere else to go, she turns to a place her brother had guaranteed would be safe: Hogwarts. Hiding in the school, Luna prepares to sink unnoticed into the mass of students and changing halls. What she never expects though is the people she'll meet, and just how far in love she'll fall for them all. Luna doesn't want to stay hidden anymore, but with family like hers, she may not have any other option.
This is the first of three books in the Girl Marauder series.
