In this mind-bending picture book for adults and kids alike, dedicated to all servicemen and women abroad, little Sally's dad has taught her an army chant about gummy bears in a letter from Afghanistan. She meets Simon when she's out camping with her mom, and shows him the two parts of the silly chant. He tells her what his daddy has taught him about how light takes a really long time to travel among the stars, carrying a picture of everything we ever do with it. Then, Sally gets a surprise that moves her so much, she passes her excitement to Simon, who now has brand new questions for his own dad.
