It's January 1986. The launch of the Challenger is just weeks away, and Cash, Fitch, and Bird Nelson Thomas are three siblings in seventh grade together in Park, Delaware.
Cash loves basketball, Dr. J, and a girl named Penny; he's also in danger of failing seventh grade for a second time. Fitch spends every afternoon playing Major Havoc at the arcade and wrestles with an explosive temper that he doesn't understand. And Bird, his twelve-year-old twin, dreams of being NASA's first female shuttle commander, but feels like she's disappearing.
The Nelson Thomas siblings exist in their own orbits, circling a tense, crowded, and unpredictable household, dreaming of escape, dreaming of the future, dreaming of space. They have little in common except an enthusiastic science teacher named Ms. Salonga—a failed applicant to the Teacher in Space program—who encourages her students to live vicariously through the launch. Cash and Fitch take a passive interest, but Bird builds her dreams around it.
When the fated day arrives, it changes everything.
