I read this in two sittings because that's just how good it was. But more than that, this is no ordinary romance book. Colleen Hoover touched on such an important subject and established a conversation on the issue through her characteres. I wouldn't tell you what it is because you have to find out yourself. You have to experience and get invested in the story and characters yourself, and that's when you'll feel dilemma.
This is such a wonderful read.
