Geek Girl and Model Misfit by Holly Smale!
I read and reviewed both of these books this month and I couldn't pick between them. They were both hilarious and refreshing, and such a fun read. I honestly can't recommend them enough and I'm just soryy I didn't get round to reading Geek Girl sooner! The characters are incredible and there's some fantastic relatable and heart-warming scenes, as well as plenty that will make you laugh out loud. Check out my review of Geek Girl here and my Model Misfit review here. I also made a book playlist for Model Misfit which you can find at this link.
Fangirl by Rainbow Rowell
This was a close thing because this book blew me away too. A book about a girl who writes fanfiction was just so exciting to read. You should all go and check it out! My review here.
