THE MESSAGE

Emberley tracks a loving mom’s text message to her child on its secondslong global journey.

The narrative begins with receipt by the sleeping child’s “two little ears.” The message glows on the phone’s glass surface, “radiating out as billions of electromagnetic photons.” Cells in the eyes detect the photons and translate their message as an electrical signal, which travels through hollow nerve cells filled with salty fluid, “straight to the brain.” Italicized science facts augment the narration: Cannily, Emberley analogizes humans’ ability to conduct electricity through nerves and salt with machined infrastructure that does so via copper wire. Emberley uses the child’s return text to further examine the brain’s neural interactivity with the phone, then broadens the overview to unpack the complex, fascinating STEM systems that support modern global communications. Emberley deftly illuminates their basics with clear language, labeled illustrations, and ongoing respect for child readers. Signature, loose-lined pictures often show both under- and aboveground activity. Rabbits scamper in tunnels as kids swing on a playground; underground cabling snakes along, unseen. Details deftly enhance child appeal. Cellphone towers are sometimes disguised as trees to blend in with local landscapes. The locations of undersea cable landings are kept “as secret as possible, to prevent sabotage,” and the cables’ “protective armor” can withstand a shark bite. Child and mother both have pale skin and straight, dark hair. (This book was reviewed digitally.)

Fascinating in scope, admirable for clarity: a winner.
