"Ferry and Wenzel strive here to build awareness...movingly illustrating the emptiness that would be felt on the planet without creatures like pangolins, rhinos, manatees, and sea turtles. The call to action—"we'll ask you for your mighty roar, to show us we are worth fighting for"—is aided considerably by the warm, stirring artwork, which invites children to reflect on the human causes of wildlife extinction and encourages them to work together for a better future." — Booklist (starred review)

"A [passionate and urgent] creature-voiced work that asks readers “for your mighty roar/ to show us we’re worth fighting for.”  — Publishers Weekly
