About the author

Amanda Cristina Ruivo

17 years old, and writing for as long as she can remember.

“Mia was born from me, but she isn’t exactly me. She gave me the courage to tell true things with a little more freedom. The stories in this book really happened; some names and details were changed to protect the people who share my life. What didn’t change was what I felt.”
— Amanda Cristina Ruivo
