The e-book version of "Minha Culpa" is available in PDF format on various online platforms, including Brazilian online bookstores and e-book marketplaces.
However, I found that there is a popular Brazilian novel called "Minha Culpa" written by Camila Lemos. The book became a bestseller and was later adapted into a film.
The book deals with mature themes, including relationships, guilt, and personal struggles, which may not be suitable for all audiences.
I'm assuming you're referring to a book titled "Minha Culpa" (which translates to "My Fault" in English). Without more specific information about the book, such as the author, I can only provide a general report.
