Write a speech, that has three reasons why Harry Potter is your favourite book.

I'm not sure why you would need something like this but I'm always down to write about Harry Potter

To begin Harry Potter was only a baby when he first defeated Voldemort, and 17 when he defeated him for food, showing that it doesn't matter how old you are you can always make a difference and save the day and be the hero.

for my second reason I give you Hermione Granger. She was the smart, compassionate witch who cared about things that most people didn't (I. e. the house elves.) and to expand on her being the brightest witch of her age (which is mentioned many times throughout the series) it encourages many young girls they they don't have to focus on their looks or what boys think because she never cared about that, your greatest strength can be you brain and that's amazing.

and finally the marauders, they were best friends who stayed close until the day each of them died. They never shamed Remus for being a werewolf, instead they embraced it and became Animagi just for their friend which one it's own is amazing, as becoming and Animagi is incredibly difficult and very few people are able to do it.
