From bestselling author Deborah Underwood comes a lively and heartwarming letter-writing exchange between the planets in outer space to show the power of perspective. It was an ordinary day for Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto, the dwarf planet. The planets were circling the Sun, staring into space, until suddenly they spot something. What could it be? Who could it be? The planets have no idea but they’re circling to find out. Whatever it is, that something is most definitely, absolutely, without a doubt NOT a planet. So begins an out-of-this-world pen pal exchange between the planets and an exoplanet. Paired with vibrant illustrations from Jorge Lacera, this STEM-friendly story, told mainly through letters, reminds readers what happens when we consider another person’s point of view. For ages 4–8.
