Twelve-year-old Halley's life is falling apart faster than the farm's leaky roof. Mom, Auntie Lynn and Spider are too busy working overtime and arguing over repairs. Her bat-crazy best friend, a volunteer at the bat sanctuary, forms the Bat Club at school with new student and child star Elektra Storm. Halley's too ashamed to admit she's terrified of bats, only to lose her temper and insult them all, leaving her feeling ostracized and alone.

A solution appears when her absentee-astronomer dad invites her on a camping trip. Halley hatches Operation Stargazer: She'll study up on astronomy and convince Dad she should live with him!

But the operation begins to go awry when Dad changes their plans, inviting neurodivergent astronomy whiz kid Leo along. Next, Halley breaks out in hives. Then Dad gets injured. Trapped behind a growing forest fire, Halley and Leo must work together to get them all to safety.
