Hogwarts: An Incomplete and Unreliable Guide by J.K. Rowling
Published August 25, 2020

The final book of the Hogwarts/Pottermore trilogy, and this one had a lot more slightly smaller entries - little snippets about the Great Lake, about the Marauder’s Map, about various headmasters and about how to get to and from the castle in the best way. As with the other two books, I really liked how the way it’s put together, the different elements linked and small additions and updates from JK Rowling herself. Not a lot to add, but it’s a good read, super quick to get through, and just adds to your Wizarding World knowledge.
