Life at Hogwarts is harder than he bargained for. With friendships forming and falling apart, family spats, midnight feasts, pranks, painful Transfiguration homework, James's Quidditch obsession, and the seemingly infinite surprises the school has waiting for them, Sirius doesn't need any more on his plate. At school, everyone has secrets, and many of them will come to light. But the mysteries he's most anxious to figure out -Remus Lupin's disappearances, what Peter is hiding, and who James Potter is on the inside- seem to be determined to stay hidden. There's a lot to learn, and unlearn, and no better place than the greatest magic school in Europe.
