I enjoyed Only Mostly Devastated, another book by the same author, and had pretty high expectations for this title going in. Perfect On Paper lived up to those expectations and then some. I absolutely loved Darcy, the protagonist, and her unlikely new friend, Brougham. Both of these characters were really well developed and I was not ready to say goodbye to them when this book came to an end. One topic that Gonzalez, the author, makes sure to convey within this story is biphobia/bi-erasure. Being in a relationship with someone of a different gender does not disqualify a person's bisexual identity. As this is a YA book, I was really excited to see this topic being addressed because it is important that teens and other young readers are conscious of this bias.
