Book five definitely has a more depressed, melancholic mood. The book covers now feature cool colors instead of the bright vibrant colors that we've grown used to. Harry is exiled and ridiculed throughout the school. Very few stand by him, including the clumsy Neville Longbottom, Luna "Loony" Lovegood, Ron, and Hermione. Dumbledore, the headmaster who has always stood by him, will now no longer speak or make eye contact with him. The new Defense Against the Dark Arts teacher, who is replaced every year, is more than willing to single him out, partially due to her boss leading the smear campaign against Harry. Events in this book bring us hope, such as the formation of the DA (you'll have to read to see!) and the Weasley twins' exit, while others, such as the death at the end, make us realize the true cost of war because yes, the Wizarding World is at war.
