YA-- A cross between alternate history, fantasy, and romance, The Gnome's Engine divertingly chases buried treasure, dallies with young noble women in reduced circumstances, and reforms a swashbuckling hero addicted to drugs, all the while pursuing a fairy's revenge. The hero and heroine are delightful, the villains various, and the hints at a history just slightly askew. Pure adventure fans may find the romanticized style gets in the way of the action, but plenty of others will find this to their liking and will want the previous title, Goblin Moon .
