Theorising Oliver Jeffers' Picturebooks: From How to Catch a Star to Now examines semiotic, affective and metafictive storytelling in Oliver Jeffers' postmodern picturebooks from a multi-theoretical approach. This volume provides fresh insight into Jeffers' iconotextual narratives through textual and visual analysis, exploring how his multimodal texts construct childhood and evoke emotional resonances. The book deconstructs the postmodernity of these narratives, highlighting Jeffers' contemporary methods of storytelling through an exploration of the texts' metafictive and self-reflective elements. From How to Catch a Star (2004) to Where to Hide a Star (2024), this book journeys through the mindscapes of Jeffers' design and analyses the nuances of metafictive storytelling from a postmodern perspective.
