Ben and Eva teach Astro the Alien about social emotional traits such as being honest, staying calm, cooperating, sharing, patience and being a good friend. Astro landed on Earth and now lives in the children’s backyard. Together they learn a lot about the world where Astro now lives. Written at a slightly higher level than the introductory Dear Dragon series, Astro the Alien books help early readers build on previous skills, expanding vocabulary and learning more complex concepts. Each book includes a note to caregivers and activities to promote reading success.
