Girl Mans Up is a coming-of-age novel written by M-E Girard and published by HarperCollins in 2016.

The book tells the story of Penelope Oliveira, a queer Portuguese American teenager who struggles to find people who will accept her for who she is.

Despite that, Gross still praises the story presented in the novel, including its "nuanced drama built on themes of identity, respect, and the desire to be recognized for who you are.
