Anderson began working on the novel in the spring, as he detailed in this Facebook post back in January:

Some good news after last week's sad Rush anniversary: I just signed the contract with @ecwpress for CLOCKWORK DESTINY, the third novel in the Clockwork Angels trilogy, based on an idea Neil had while working on The Percussor's Tale. He and I brainstormed the story but he knew I'd have to write it without him. This is being done with the full approval of his wife. I'll start writing this spring.

Anderson and Peart co-wrote the first 2 novels in the Trilogy - Clockwork Angels and Clockwork Lives - in 2012 and 2015 respectively. The books are based on the story and lyrical concepts created by Neil Peart for Rush's 2012 Clockwork Angels album.
