Dan Mackmain, the son of a dryad and a mortal man, is given another job by the Green Man, but he has to figure out exactly what the job is before he can do it. We’re about halfway through the book before Dan discovers the real (urgent and dangerous) problem, but not to worry there’s plenty of action right from the start including a bunch of pickaxe wielding kelpies in search of lost property. The stakes get higher as the book progresses, and Dan brings in help from a lot of the characters we’ve met in earlier Green Man books, ones who have a foot in the human world and the magical one. Besides kelpies, expect swan maidens (and men) dryads, wise women and cunning men, not to mention dangerous hags and a main antagonist who might be impossible to overcome… but Dan has a plan. As usual Ms McKenna keeps up the pace, the interest and the danger while showing a vast understanding of British folklore and traditions. I had this as an advance reading copy from the publisher. It’s due out on 15th November, and well worth reading – though if you haven’t read the other Green Man books (starting with Green Man’s Heir) I recommend you treat yourself and start from the beginning.
