Earth to Stella by Simon Puttock, illustrated by Philip Hopman is a very creative bedtime book.  Stella’s father is trying to put her to bed, but Stella is pretending that she is traveling through space.  Her father calls to her:  Earth to Stella! and his messages get incorporated in her imagination.  The illustrations are fun and the text is straight-forward and clean.  I especially liked that this was a space-crazed little girl, rather than a little boy.  Preschoolers will enjoy this story, because they will all recognize how they can get caught up in their imaginary worlds.  The story ends with Stella’s father joining her when she heads back out to space.   Perfect for space-themed storytimes or bedtime ones.
