This doesn’t look like your typical ‘hard science fiction’ cover, but I love it. It has that lovely limited color palette, and while the silhouettes don’t offer much detail, we don’t need much detail. We know there’s an ensemble cast, and it has a YA feel to it (as does the subtitle). The diagrams in the background inform the science in the story. The font is simple and san serif, like most science fiction, but with a subtle coloring that melds into the cover art while still being strong.
