A year after the events of the last book, the Wizarding world is in ruins. Voldemort has taken over, the Ministry is corrupted and even Hogwarts has been infiltrated. Dumbledore is gone, the Order in hiding and Harry hasn't the first clue as to where to begin the hunt for Horcruxes. Siri is tired. A year in France and finally she's returned. But she's not the same, and she has a secret. The Boy Who Lived and the Girl Who's Fighting Fate reunite for the last time. Book 4 of 4.

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.

Siri and Harry are back. Returning to their fifth year at Hogwarts, there's going to be some major changes. Between new Defense Against the Dark Arts professors, new friends, and new love. Not to mention the war that's slowly growing larger and more dangerous everyday. The next months at Hogwarts will be interesting, but it's nothing the duo- along with the help of the ever brilliant Hermione and always loyal Ron- can't handle. Book 3 of 4.

Messrs Moony, Wormtail, Padfoot, and Prongs certainly feel quite accomplished after completing what they dub as the Marauder's Map. A map designed to show every classroom, hall, corridor, and even secret passageway of the Hogwarts Castle but also capable of identifying every person, ghost, and poltergeist roaming about. Or so they thought. It takes Elspeth Hayes casually strolling down the corridor one afternoon for the boys to realise that she's not showing up on the map and they want to figure out why. But Elspeth is not about to give away her secrets so easily, after all, a girl has to have her secrets to keep the boys on their toes.
