Honor Girl by Maggie Thrash was my favourite book of 2015. This was a graphic memoir, which explored Maggie's time at a summer camp. This was the year she first realised she was a lesbian. It's a fantastic story, exploring a lot of different themes. The ending stayed with me long after the book ended.
I absolutely adore the cover work. Her artwork is simple, but I think it makes her story more powerful. Despite the simplicity she plays around with the design and my favourite panels in chapter four include two different speeches running into one another.
I messaged Maggie Thrash on tumblr to express my love for her work and she was so nice in her response. She's a lovely author and you should check this book out before her first work of fiction comes out next year.
