I really loved this book. At first, it reminded me vaguely of Thirteen Reasons Why by Jay Asher, just because of the plot: the suicide of a main character who has left behind a part of themselves. However, this book was very different from Thirteen Reasons.
At the beginning of the book, I didn't quite understand Ingrid. I couldn't understand why a seemingly happy girl would just kill herself, similar to Caitlin. But when Caitlin found Ingrid's journal, it opened up an entirely different point of view. I started to understand Ingrid, and not just her suicide, but her life and who she was. Along the way, Caitlin slowly started to make new friends, and discover that she could, in fact, live without Ingrid while remembering her, too.
One part in particular was important to me in this book. When Ingrid just writes in her journal how she's scared she's crazy, and you really start to feel her fear, her anger, and sadness. It's important because it gives a reason behind Ingrid's suicide.
I loved this book a lot, as I've previously mentioned. It's a story about grief, loss, and most importantly, the real meaning of friendship.
