I heartily recommend The Wood Fire Handbook - The complete guide to the perfect fire by Vincent Thurkettle.
Its great if you're thinking of getting a wood burner or real fire or already own one giving you pointers on what kind of commitment you'll need to make such as wood storage, seasoning, storage, splitting and more.
Where it excels is the author's love of burning wood. He describes burnt different types of wood as if describing the bouquet of fine wines.
The chapter on campfires and wood fire cooking is good for forest schools but my favourite is a good laymen description of the science of fire. He compares heat output from flames to embers. Very interesting if you own an ultra efficient stove like mine (pictured) that uses secondary overfire air to get complete combustion of smoke.
The author has worked in forests all his life and is a repository of down to earth practical information and anecdotes.
The nicest touch is the end quote.
