I recently finished listening to the audiobook of Where She Went by Gayle Forman. Where She Went is the sequel to If I Stay. I enjoyed the first book, but this second book was phenomenal. I loved it. First, I enjoyed that the book was told through Adam's perspective. (I might be a little exhausted of female YA narrators.) I liked that it's a slow burn to learn about what happened with Adam and Mia since the accident. I love the characters. The author even managed to catch me a little off guard with how the story wrapped up. I loved the details, description, and the shooting star lyrics at the start of the chapters. Magnificent! If you are looking for a great contemporary ya book, check this one out. Here's the link to it on Amazon.
Sidenote - You should probably read the first book beforehand, although I think it stands well on its own.
