First Second’s opening release of the winter is the latest title in their Science Comics series of science-oriented non-fiction graphic novels for middle-grade readers. Since this one tackles the subject of polar bears, it also comes face-to-face with global warming.

“It’s about two polar bear cubs learning how to be polar bears from their mom, and it talks about the degradation of their environment,” Brill tells EW. “But it’s coming at it from a really optimistic point of view. The book lays out all these challenges, but it also talks about all the things humanity can do to slow down and maybe even reverse global warming.”
