A girl mails a letter to space and gets a physics lesson back. Galileo drops balls from towers, the moon falls forever without landing, and Isaac Newton stares at apples until the whole sky makes sense. Iris Fennimore turns gravity into a detective story for curious kids around eight to twelve, with each chapter building the next clue. Duncan Winslow reads it like a patient uncle who still gets excited about pennies spiraling into funnels, his calm voice making the math feel like magic you can actually understand.
