The book is a YA murder mystery. This book is about this girl trying to solve her boyfriends murder. The murder takes place on their college campus. I remember that her boyfriend was on the soccer team. The police question her and this other girl who disliked her boyfriend. Throughout the book the main character recalls past experiences she's had. In one flashback she mentions that her boyfriend got into a car accident and hurt a kid. He feels guilty so he visits the boys house often. Later in the book we learn that the girl who hated the mc's boyfriend is the boys (the one involved in the accident)older sister. *Big spoiler* at the end of the book you learn it was the second girls boyfriend that killed the mc's boyfriend.
I read this book around 2016-2019. The author is a female and I read this as an ebook. The book is in english and it is based in the 21st century.
