Welcome to the Heartbreak Museum. Or rather Penelope Marx's private museum that she created after dealing with a devastating and heartbreaking phenomenon known as Heartbreak. Heartbreak comes in many forms: Keats, the perfect charming handsome guy, Cherisse, the world's worst girl whose purpose in life makes Penelope languish, Audrey Penelope's best friend who is getting further and further away, and Eph, the annoying and admirable best friend who has lately confused Penelope even more. But, the thing that breaks us the most sometimes is learning to let go of the good times before realizing that what we have is not always going to be okay.
