"Tillie Walden is the future of comics, and On a Sunbeam is her best work yet. It's a 'space' story unlike any you've ever read, with a rich, lived-in universe of complex characters." -Brian K. Vaughan, Saga series and Paper Girls
"On a Sunbeam is a rare treat. It's both a slow-burn romance and a found-family space opera adventure with an engaging cast of characters. But it's the world building that really stands out, with a blend of SF and fantasy in a gloriously strange setting that is so brilliantly original I have no idea how to describe it. I enjoyed every bit of it." --Martha Wells, author of The Murderbot Diaries and The Books of the Raksura
"Enthralling, beautiful, and compelling. I couldn't put this down." --Ann Leckie, author of Ancillary Justice
"On A Sunbeam strikes a magical balance between trippy and tangible, heartbreaking and hilarious. It was so easy to curl up in the art and lose myself in the story." --Becky Chambers, author of The Long Way to a Small, Angry Planet
