How Does On A Sunbeam End?

The ending of 'On a Sunbeam' by Tillie Walden is this beautiful, bittersweet crescendo that ties together the emotional threads of the story in a way that feels both satisfying and achingly real. Without spoiling too much for those who haven’t read it, the final act brings Mia’s journey full circle as she reunites with Grace, the girl she loved and lost during her school days. the reunion isn’t some grand, dramatic spectacle—it’s quiet, tender, and deeply human. Walden’s artwork shines here, with those sweeping, dreamy panels that make the cosmic setting feel intimate. The way Mia and Grace finally find each other again, after years of separation and longing, is just... chef’s kiss. It’s not a perfectly neat ending—there’s still this lingering sense of life moving forward, of unresolved edges—but that’s what makes it so powerful. It’s hopeful without being saccharine, leaving room for the characters to keep growing beyond the last page.

What really stuck with me, though, is how the story wraps up the themes of found family and healing. The crew of the ship Mia travels with—Elliot, Alma, and Jules—become this makeshift family for her, and their bond feels as central to the story as the romance. The ending doesn’t abandon that; instead, it weaves those relationships into Mia’s reconciliation with Grace, showing how love and support can come from unexpected places. And the setting! The way Walden uses this sprawling, melancholic universe of abandoned spaceships and forgotten ruins to mirror the characters’ emotional states is genius. The final scenes on that mysterious, crumbling structure—where Mia and Grace finally meet—feel like a metaphor for rebuilding something broken. It’s one of those endings that lingers in your mind for days, not because it’s flashy, but because it’s so earnestly heartfelt. I closed the book with this weird mix of joy and wistfulness, like I’d said goodbye to friends.
