Grumbly-Grumbly

When thunder and lightning reveal a hidden, magical secret

Mom and the twins read a story together every evening—their very special bedtime ritual. But when it suddenly thunders and crashes outside, the siblings hide fearfully under the blanket. Many children know the fear of thunderstorms! That's when Mom shares the legend of Grummeldi-Grummeldi (Grumble-Grumble)—a magical story that gives lightning and thunder a completely new meaning.

Sarah Mars tells a tale in poetic language of loneliness, empathy, and the great power of friendship. The story sensitively shows how an outsider discovers their perceived weakness as a unique gift for doing good. The illustrations by Aicke-Wulf Linsner and the interactive windows make this premium board book a special journey of discovery. Because behind the flaps, a second secret is revealed: the hidden world of the Lunaria, tiny beings that exist right alongside us.
