This week’s Picture Book Postcard is from An Astronauta of If Your Abuelo Is an Astronauta.
This hilarious, high-flying bilingual picture book from the creators of If Your Babysitter Is a Bruja captures the love between grandchildren and long-distance grandparents, the complicated relationship between siblings, and the power of imagination.
The day before abuelo comes to visit, his grandson knows there’s more at stake than meets the eye. Abuelo comes from very far away, an astronauta from a distant planet, and his time in orbit is limited and very special. If the boy wants to have time for exciting aventuras, he must defeat the Space Invader before his abuelo’s ship touches down.
As AstroKid, he ships the Space Invader off to Mars, battles her on Pluto, and chases her through asteroid showers—whatever it takes! Only…what happens when his plans work too well and Space Invader—his annoying little sister—retreats?
