From New York Times bestselling illustrator Dani Jones comes a heartfelt exploration of sisterhood, forgiveness, and outer space invasions. Mary Seaver lives in her own world. It's not her fault if sometimes her enthusiasm creates chaos. To Mary, that's what being 10 years old and a huge science fiction fan is all about. Allison "Al" Seaver is Mary's older sister--and she's everything that Mary is not: cool, calm, collected, and super popular. So it makes sense that when aliens invade their hometown of Pleasant Valley, Mary's trying to warn everyone about the end of the world while Al's just hoping it will all go away before the spring dance. But when a secret emerges from their family's past, Mary and Al find themselves turning to their most unlikely ally: each other. Dive into Dani Jones's debut original graphic novel, a hilariously tender investigation of sibling dynamics, aliens, and what it is that makes us human.
