This book is full of lots of action and twists. The Zombie plague is pretty much in the background, so like our current situation, but there is a plot afoot that Maurice and Veronica must stop and they must save Veronica‘s sister. The darkness is spreading and Queen Victoria‘s most loyal agents must decide where they stand-on the side of the Queen or the side of the future of England. 3/5 stars, read if you like steampunk and/or Sherlock.
