Stellaluna
A baby fruit bat is knocked from her mother's grasp by an owl and grows up in a bird's nest, learning to fit in before joyfully rediscovering who she really is. The story is warm and fully resolved, with its one tense moment right at the opening and nothing but gentle discovery after that.
Ideal as a read-aloud for ages 4 to 7; confident independent readers from about age 6.
Chapters to know about
An owl attacks Stellaluna's mother in flight, knocking the baby loose; the perspective can make it briefly look as though the mother has been harmed. The moment passes quickly and the rest of the book is calm.
Stellaluna falls alone into the night and lands in a bird's nest, establishing the separation-from-parent situation that drives the whole story.
Stellaluna quietly gives up bat behaviors one by one to please Mama Bird; children who feel pressure to fit in may find this section especially affecting.
