I'm not sure specifically as I haven't read it. But generally, a graphic novel like this might be about a story set on water, perhaps a nautical adventure, with some kind of 'fire' element being a central part of the plot, like a ship on fire or a conflict involving fire on the water.
I don't know as I haven't read it. But it could be a group of sailors, pirates, or people living near the water. Maybe there's a brave hero who has to deal with the 'fire on the water' situation.
