These Vengeful Souls by Tarun Shanker

England, 1883. On the run with the grieving Sebastian Braddock, Evelyn wants two things: to be reunited with her friends, and to get revenge on the evil Captain Goode. Not only has he misused his and Sebastian’s powers to rack up a terrible death toll, but he’s also completely destroyed any hope of Evelyn or her friends regaining the life they once knew.

Evelyn is determined to make Captain Goode pay for what he’s done, but is her revenge worth risking the lives of Sebastian and her friends? Or is it better to flee the city and focus on staying alive? And with the Captain spreading lies about Sebastian in an attempt to flush them out of hiding and turn the populace against them, does she even have a choice at all?
