The Clockwork Heart series by Dru Pagliassotti is set in Ondinium, a city built on a mountainside where society is divided into strict castes and governed by a giant analytical engine called the Great Engine. Taya, an icarus who wears metal wings and delivers messages across the city, rescues a diplomat from a deadly crash and finds herself caught between two brothers from the ruling caste. One is reserved and intellectual; the other is charming and politically ambitious. As Taya digs into the circumstances of the crash, she uncovers a conspiracy that goes to the heart of how Ondinium is governed.

The first novel was published in 2008, and EDGE Science Fiction and Fantasy Publishing released the complete trilogy in 2014. Clockwork Lies: Iron Wind takes Taya and her allies outside Ondinium’s borders, while Clockwork Secrets: Heavy Fire brings the story to its conclusion with full-scale conflict. The series blends romance, political intrigue, and detailed steampunk worldbuilding, with Taya’s working-class perspective providing a clear-eyed view of a society that prefers to keep its lower castes out of sight.
