Boggart And Fen 
Number 3 in series

Mallmoc’s towering iron land-ship is cutting a devastating path through Liofwende. Flanked by an army of Ulcugga fairies, the evil warlock appears unstoppable. His only foes are a boy from England, a boggart and a talking rat with a food fixation. Or so he believes. Word has yet to reach his ears of the faerie armies that march to confront him, or of the gnomes devising a cunning scheme to waylay his terrible machine. All Spiggot and Jack must do is buy these allies some time … but how?Boggart and Fen is the spellbinding conclusion to one of the warmest, most compelling fantasy series of recent years.
