Obviously, as a reader, you know how this book ends, so the story is really why they broke up. Minerva (goes by Min) has a box of mementos from her relationship with Ed (honestly, what girl doesn't collect things like that, or maybe it's only during their first relationship, like me). The whole story is her going through each item in the box, starting with the beer caps from the first time they talked and he asked her for her number, to the rose petals lining the bottom of the box, obtained from the florist during the break up. It is a compelling story and will make everyone remember their first love and the pain they felt during that time of betrayal/loss. I thought this book was very interesting, and also sad, and kind of odd that it is told from the POV of Min while the author is a male, but whatev.
