In doing so, she sets off a chain of events that reveal a larger plot. Colt works for the Bureau of Investigation (BOI) that hunts down dangerous monsters- and they are definitely interested in stopping the last siren. When they think that they may have found her, Colt, who is immune to a siren's voice, is sent to get her.
What I loved: The time is well built including slang of the 1920s, and the world building around the monsters is really interesting and adds an unique new twist on the historical fantasy plot. The book moves quickly with a lot of action as the events spiral once Eris begins to learn about who she is.
What left me wanting more: There's some heavy instalove here, and a lot of dangerous scenes with back-and-forth saving that move a little too fast for my taste. I would have liked to slow it down and get a slower taste for what is going on and who Eris and Colt are.
Final verdict: ROARING would be great for people who like historical fantasy with fast-paced plots full of action.
