There are so many things that Mia hates about boarding school. So, so many. So she gets kicked out. But not before she falls in love. Now she's a crew-member on a spacecraft that travels to distant planets to restore beautiful, broken-down structures. But even as she grows closer with the crew, she can't help but remember and dream of the girl she met in boarding school - and hope to meet her again someday. Part love story and part epic space adventure, On a Sunbeam is a masterpiece from an explosive, unmissable talent. Tillie Walden's inimitable style is gorgeous as she tells a story of sexuality, gender, first love, and awesome cats.
