Slow Demons by Chris Paton

Studying the precise art of chronology, scientist Luise Hanover is in the process of manipulating time. As her work attracts the interest of foreign powers, Luise is drawn into a fast-paced and chaotic world of shadowy alliances, exotic characters and the madly competitive world of steamracing.
In the shadows and on the streets of London, Luise turns to the only person she can truly trust, Hari Singh and his sulky hawk, Shahin.
Slow Demons is a Steampunk Adventure set in London in the 1850s full of weird machines, exotic characters, dirt, engine grease and demons. From Goodreads.

This was even better than the first book in the series though I did miss Jamie. Instead there is Jamie's sister Luise who soon gets acquainted with Hari which leads to a lot of trouble. The demons are an interesting concept and I am looking forward to see where all this is leading to. This book has a wee bit of a cliffhanger and I am wanting to read the next book now.
