Honestly, I have NO idea why this seemingly simple, straightforward book about a girl having to choose between life and death could be so impactful on me.I mean yes, I didn't expect a light read., but I would never have expected to be so floored by or feel so emotional about this book.If I Stay is a very beautifully written book with thought provoking moments and compelling relationships. From her grandparents to her best friend, to her brother and her boyfriend, I was equally invested in all of them. Mia is somehow extremely relatable to and that was probably what made me so invested in her character, her relationships and most of all, her choice of whether to stay or to go. To say that this book is emotional is like an understatement. Reading it brings out a flood of different emotions in me and this was something that really took me by surprise.
