';A charming, tender, and hilarious debut you will want to get lost in.' Gayle Forman, bestselling author of If I Stay and I Was Here

In this ode to all the things we gain and lose and gain again, seventeen-year-old Penelope Marx curates her own mini-museum to deal with all the heartbreaks of love, friendship, and growing up.

Welcome to the Museum of Heartbreak.

Theres possibly the worst person in the world, Cherisse, whose mission in life is to make Penelope miserable. Theres Penelopes increasingly distant best friend Audrey. And then theres Penelopes other best friend, the equal-parts-infuriating-and-yet-somehow-amazing Eph, who has been all kinds of confusing lately.
