Specifically books and other sources about fire, but mainly books. (that I can buy as Christmas is coming up.)
The Anatomy of fire. Like, I know fire and flame generally has a structure, like a diagram of a burning match, how does this change with materials and circumstance? Have Doring Kindersley done a giant book of fire?
The Ecology of fire.
What books do firefighters read when they train?
Forest Fires, what is it like to be inside one, exactly how do they work? ( have read the major wikipedia articles on this stuff, I am looking for more detaile, and more piquant, information.
The same for firestorms.
Especially any old books on fire and how we used to think fire worked. (Writers from around the 16th and 17th century had more interesting prose and their pseud-scientific ideas and perceptions carry a lot of imaginative fuel.)
Poetry about fire. Did someone do a Conference-Of-The-Birds thing except everything is on fire?
Did some crazy visionary write a whole book in a world of fire Voyage-To-Arcturus style and I missed it?
Any Project Gutenberg reports or stories about it?
