Clockwork Heart is just what I want in a steampunk novel: enough clever inventions to keep things interesting, not so many that the story gets bogged down with them. Taya, the heroine, is an Icarus: trained as a messenger, she soars over her city on light metal wings carrying news and packages from one sector to another. Everything changes when she pulls off a dangerous mid-air rescue of two high-ranking passengers in a wire-rail crash. Suddenly Taya has caught the attention of a handsome politician, a bad-tempered clock maker and a circle of terrorist engineers. Much drama ensues.
