Oseman is the author of four YA novels: Solitaire, Radio Silence, I Was Born for This, and Loveless. Heartstopper is a prequel to Solitaire, showing how the relationship between two of the supporting characters developed before the novel began. Oseman first published Heartstopper online as an e-novella, then developed it into a webcomic that in turn was published in print in the UK. It has been optioned for television by See Saw Films.
While most Graphix titles are aimed at middle-grade readers, the imprint has recently broadened to include YA graphic novels, such as Jarrett Krosoczka’s Hey Kiddo. Like that book, Heartstopper is rated 12+.
