Grant Snider is one of the best comic strip illustrator/writers around. He writes for adults but also for children, and it’s with the latter that he shines. His previous book, “What Color Is Night?,” is my favorite book to read to grandchildren. The follow-up, “What Sound Is Morning?,” hits the same sweet spots: a lovely tale of morning sounds, scenes, and activities; a focus on morning sounds; intricate, evocative drawings; lyrical text that challenges children and keeps adults satisfied; and a beautiful palette of early morning reds, yellows and oranges. Somehow Snider captures fully the pregnant promise of dawn and the early morn. “What Sound Is Morning?,” like its predecessor, is destined to blossom into a classic.
