This is a good start/intro to the Cosmic Balance series. Though I'm a little disappointed it appears we will be following a vengeance/trickster demon (Megan) in the rest of the series and Serafina will only be a secondary character. We only meet Megan briefly, so I hope she is as engaging as Serafina.

I like Serafina as a heroine. It's the first time I have connected with a demonic character, usually those storylines don't interest me as much. But I empathized with her plight as an outsider and it seemed like she was coming into some very interesting powers. She could definitely put those to good use given the character of the fae in Duesling where she was raised.

Eldon was a decent male lead, he was not the focus of the story (not the hero per se) so I didn't get super attached. However I loved his pet dragon, Trust. I hope we will see more of him in the future.

The world building in this prequel is unique and I look forward to seeing it develop as more books are released. The characters are on the cusp of new adulthood, so I think future books will be in the new adult age range (for those readers who shy away from YA). I received an advanced copy of this book in exchange for an honest review. 4 stars / No heat. ( )
