There are many reasons you should read Tillie Walden’s On a Sunbeam. The pitch-perfect plot, characters, pacing, and color palette combine to deliver a feels-worthy sci-fi epic.

But because On a Sunbeam is so good (and you’ll likely fly right through it), you might not notice how much characterization Walden’s lettering adds to the story. The dialogue throughout On a Sunbeam does a ton of work, letting readers in on characters’ emotional states and cementing their personalities.
