Harry Potter and the Goblet of Fire
I loved reading The Goblet of Fire, this is mostly down to the creatures and other wizarding students we meet in the novel. As a lover of Hogwarts it's interesting to know what other wizarding schools are like and to explore further the seemingly endless list of creatures.
I can never find a boring or uninteresting moment in The Goblet of Fire and I never get sick of reading it again and again as it's so easy to lose myself in Harry Potter with the astounding events and distinctive characters. I really like how Hermione Granger strives through in this book as not just a clever girl, but as a girl with passion and determination. I like her complex personality; normally she is typecasted into just being 'intelligent', but Hermione is shown with a more girly and emotive side in this book, giving her more depth than just being Harry's clever friend. She is well-rounded and is more accessible as a regular person (though a witch) with feelings and a personality.
In this book we regularly come across Cedric Diggory, a Hufflepuff, who allows us to see the Hufflepuff house in more depth rather than just briefly touching upon it as it has been in other books. I like how we can see the fairness Cedric strives to uphold throughout this book, showing us the value of Hufflepuffs.
Anyone who hasn't read up to The Goblet of Fire should definitely re-think that decision as this is the book where it all changes and it's then impossible to not continue reading the rest of the books.
