I'm not sure specifically as I haven't read it. But generally, a graphic novel might be about a character named Deadbird and could involve some sort of adventure, mystery, or personal journey.
A 'deadbird graphic novel' could potentially tell a story related to a dead bird in a symbolic way. Maybe it's about the cycle of life and death, or it could be a metaphor for something lost or ended in a more complex narrative that unfolds through the graphic format.
