I have looked forward to this book ever since I first heard about it, which was 2010. When I sat down to read it, I was a bit worried that it wouldn't live up to my expectations. To my delight, that didn't happen.D.B. Jackson's writing sucked me in from the start. Sometimes it felt like I was walking next to Ethan as he navigated the lanes of Boston. The story felt well researched, from the careful description of the houses and streets of London, to the historical events that happens in the background. But the tension between the people loyal to the crown and the rebels creeps into the story, but it doesn't overwhelm it.The magic that Ethan use felt unique. I loved how it could use several different sources for power, and what it cost. But, I also liked how the history of witch trials affected the attitude of others.The mystery at the center of the plot was intriguing, and I loved how Ethan felt a bit out of the water, since he isn't used to dealing with the wealthy of Boston. There was setbacks, of course, and I liked how they felt right, as if the author had carefully selected them to create as big problems as possible for Ethan. Despite that, the only major problem I had was with the lack of variation when the villains, both Pryce and the Conjurer, puts up obstacles in Ethan's way. Yet the obstacles used fit their personalities.
