This book is one of the strongest installments in the Harry Potter franchise, but it is also one of the most mature. There are many mature themes, such as snogging (making out), various crushes, a few heartbreaks, a lot of bloody violence, many deaths, and some scary images. There is also a lot of alcohol mentioned, including Butterbeer, Firewhiskey, Oak-matured mead, and wine. Many adults get drunk in this book, which greatly impairs there judgement. On a better note, there are many good things about this book. There are many good role models, including but not limited to: Harry Potter, Hermione Granger, Remus Lupin, Albus Dumbledore, Minerva Mcgonagall, and sometimes Ronald Weasley. Harry is brave and loyal, Hermione is smart and uses logic, Remus is a good overall figure, Dumbledore is loving and gentle, Minerva is the parental figure, and Ron is the loyal friend. Other positive messages include friendship, love, loyalty, bravery, wit, dealing with losses, heartbreak, and generosity. Overall, I rate this book five stars and say it is iffy for ages 12 and under.
