“… always look, / really look / when it’s dark out.” A dark-haired child and adult woman of indeterminate race explore bioluminescence in the night, from foxfire and fireflies to a host of water creatures, in a picture book sure to inspire wonder. The brief primary narrative is only a few sentences long, with many page spreads featuring only a phrase. This is supplemented by a paragraph in smaller font that provides information about the organism or animal pictured. The illustrations in this informational picture book truly shine, with matte black backgrounds that make it seem as if the fascinating bioluminescent creatures shown are truly luminous.   (Ages 4-8)
