Somehow it’s been 15 years since the publication of David Small’s graphic memoir Stitches. To call it a debut would be inaccurate; at that point, Small had already amassed a storied career as an illustrator of books for younger readers, including multiple collaborations with his wife, the writer Sarah Stewart. Stitches, the harrowing story of Small’s experience with cancer treatment and unexpected surgery during his teenage years, was a haunting work, one that immersed the reader in its creator’s body and mind during a turbulent period.
