Lake (Trial of Flowers
) envisions the universe as an enormous clockwork, put in motion by God, complete with gears and a mainspring hidden at the Earth's center, in his intriguing first trade hardcover novel, a fantasy set in the magic-tinged late 19th century. Archangel Gabriel charges clockmaker's apprentice Hethor Jacques with a quest: he must find the lost Key Perilous so that the Mainspring of the World can be rewound. Hethor leaves New Haven, Conn., for Boston, where he boards Her Imperial Majesty's Ship of the Air Bassett
and travels south to the towering Equatorial Wall, along the top of which run the great gears that rotate the earth. Hethor soon discovers opponents who don't want the mainspring rewound. He must deal with dark magicians, monstrous winged savages, mechanical men and other wonders during his epic journey, which takes him over the wall and into a land of wonders. The author of more than 200 short stories, Lake demonstrates his enormously fertile imagination in this unusual book, marred only by some sluggish pacing. (June)
